The One Lumix to Rule Them All: A Panasonic GX7 Full Review

The Panasonic Lumix GH3 has been the undisputed flagship of the Lumix mirrorless series since November 2012. Though it is mirrorless, it bears a strong resemblance to low-end DSLRs in terms of size and design. The GH3’s thickset package is meant not just for stills but professional video making as well. In fact, it is widely considered one of the best compact bodies for video by professional videographers.



However, the GH3’s status as a “video camera rather than a stills camera” left a gaping hole in the Lumix mirrorless line-up for photography. While its Micro Four Thirds partner Olympus had already released the professional OM-D E-M5 months before the GH3, and was on the verge of releasing the high-end Pen E-P5, Panasonic still had very little to offer in terms of high-quality compact still bodies. Not providing one would result in being left behind by the competition.

Enter the Lumix GX7, Panasonic’s first serious contribution to the compact mirrorless camera market for professional photographers. It is the successor to the two-year-old Lumix GX1 in name only – everything else about this camera has been greatly improved or changed, hence the leap from 1 to 7. Having used it intensively for more than a month now, I can say with confidence that Panasonic has created the perfect professional body which can be used by photographers who are tired of carrying around a lot of excess gear.

Is it the best mirrorless camera on the market today for stills? You’ll have to read on to find out!

Design, functionality & ergonomics

The GX7 is an extension of your hand…

DSC-RX100M2, 1/160, f/ 18/10, ISO 3200
One of the most ergonomically friendly cameras I’ve ever held.

The first time you grab the Lumix GX7 out of the box, you really feel as if it is an extension of your hand. Your pointer finger lands comfortably on the front dial/shutter button, your other fingers slip snugly into the prominent grip, and your thumb settles nicely on the rear thumbwheel and the on/off switch. All dials, buttons and switches are in easy reach and have been thoughtfully positioned.

DSC-RX100M2, 1/80, f/ 18/10, ISO 3200
The buttons and dials are perfectly placed.

I won’t go into all the specifics as there is an official manual for that but I would like to touch upon a few buttons I really like using – mainly the AF-MF switch and the Fn1/Q menu button.

The former is allows you to easily switch between AF and MF mode without digging through the menu. The GX1 used to have an AF-MF button to change the focus mode but I find the switch more convenient and also more conveniently-placed on the rear of the camera. I often shoot butterflies and frequently find it necessary to jump to MF mode if the AF won’t lock onto a certain part of the butterfly.

The latter is the same found on the GH3. It gives you access to all the main functions of the camera on one well-organised screen. Again, this allows you to sidestep unnecessary menu digging if you’re in a hurry. (That said, I should mention that menu-digging isn’t really a chore on Lumix cameras, as their menus are among the best. The mix of specific eye-catching colours and large text makes them simple yet very clear to understand and navigate.)

You will notice that the camera has been designed with enthusiasts/professionals in mind: you’ll easily and I would say naturally find all the most important buttons such as White Balance, ISO sensitivity, and burst mode. There are also four function buttons that can be customised with your desired settings. The only button placement I didn’t like was the LVF/Fn4 button, as it is too close to the built-in viewfinder, making it awkward to reach with respect to the others buttons. But it is a minor flaw we are talking about here.

Since a picture (or three) speaks a thousand words, here are a few images of the GX7’s excellent build and button placement.

Despite being only a tad taller and longer than my iPhone 3G, everything has a place. Nothing is crowded and there aren’t any superfluous buttons or switches. It is the acme of a functional yet minimalistic design.

The best built-in EVF on a compact mirrorless?

The tilting EVF
The tilting EVF on the GX7

Mathieu and I have always been pretty divided on the subject of viewfinders. Personally speaking, I rarely use viewfinders on any camera except in situations where I want to keep the camera very steady. Mathieu, on the other hand, cannot be pulled away from a viewfinder if it is present on the camera.

In the case of the tilting EVF on the GX7, I was able to appreciate its excellent resolution, accurate colour reproduction, impressive refresh rate, 100% field of view and intelligent right-hand placement on the body. Most of all, I was amazed at how it didn’t impact the compactness of the GX7 body at all, unlike the Pen E-P5’s external VF-4 which, as wonderful as it is, protrudes like a sore thumb. However, I found no use whatsoever for the tilting function as I much preferred the tilt-touch LCD for awkward shots. (Let’s just say I’m not a fan of doing acrobatics in the name of photography!)

Mathieu will tell you a different story. He often found himself using the tilt function on the EVF especially when he was composing artistic shots or trying to remain discreet on the streets. He reminded me of a modern male-version of Vivian Maier, with his gaze constantly locked downwards into the viewfinder, in search of the perfect scene or moment.

In the end, I guess it all comes down to whether you are a fan of viewfinders or not. If you love them, you’ll really enjoy the EVF on the GX7. If you can live without them, you’ll find it a nice addition for extreme circumstances as I do. Either way, it’s a win-win situation.

Image Quality

Micro Four Thirds isn’t so ‘micro’ after all…

DMC-GX7, 1/50, f/ 5.6, ISO 200 - From RAW

We all know that photographers tend to get really hung up on sensor size. “If it ain’t full-frame, it ain’t worth framing,” would be the adage. However, what a lot of professionals and advanced amateurs don’t know is that the Micro Four Thirds sensor has come a very long way in terms of image quality. Sure, it will never match the depth of field generated by a f/1.4 portrait lens on a full-frame Nikon D800 nor the low-light performance of a Nikon D4, but do most of us really need that for our day-to-day work anyway? (For a good read about this contentious subject, head over to this excellent post by Lindsay Dobson.)

DMC-GX7, 1/1000, f/ 8/1, ISO 200
DMC-GX7, 1/1000, f/ 8, ISO 200

The Lumix GX7 has really pleased us with its image quality so far. The sensor is new compared to the one found on the GH3. For those interested in technical details, this sensor has larger photo diodes compared to previous Panasonic MFT sensors. But what is a photo diode? It is the part of the sensor that converts light into an electronic signal. The sensor is composed of micro lenses on its surface and each ray going through the micro lenses hits the photo diodes. Being larger on the GX7, they can capture more light. This is why the GX7 should deliver better image quality in low-light conditions and have a better dynamic range.

How this can be translated in a real world situation?

Well, after several comparisons (combined with the innate feeling a photographer gets when using this kind of equipment daily), we can say that these improvements are hardly noticeable unless you view your images at 100% or find yourself in need of extreme ISO performance.

Starting with high ISO performance, we can see that the GX7 performs better at high ISO starting from 6400 and up in comparison to older sensors on other Panasonic and Olympus MFT cameras. With the GH3, the differences are minimal. At 6400 ISO, you will notice that the noise on the GX7 is finer and that it renders the shadows better.

In comparison to the E-P5, you may notice that the sensor has more sensitivity as the pictures are brighter with slightly more details in the shadows and a better colour rendition. Also note that the differences in colour between Lumix and Olympus cameras can be related on how the Auto white balance is calibrated. Of course, the differences regarding colour and contrast can be remedied in Lightroom or another RAW developer software.

E-P5, 1/320, f/ 3.5, ISO 6400

You can check out more high ISO comparison shots between the GX7 and E-P5 here.

Compared to a newer sensor such as that in the OM-D E-M1, the performance appears practically identical regarding the amount of noise and details preserved. Overall, the GX7 tends to give a less yellow/greenish tint to its images.

So what you really need to know is that the GX7 has one of the best MFT sensors around today in terms of high ISO sensitivity. Its superiority to older MFT sensors becomes the most visible at 6400 ISO and above.

Below is a small gallery of images taken between 1600 and 3200 ISO of the festive ‘Luci D’Artista’ in Turin. I generally don’t go above these values since the internal stabilisation of the camera allows me to reach some fairly slow shutter speeds. (More about that below!)

Concerning Dynamic range, the improvement is less noticeable. You need to compare extreme situations but I didn’t notice a substantial improvement in comparison to other MFT cameras. What I can say is that the camera defends itself very well and the RAW files give you lots of flexibility if you want to increase the highlights or decrease the shadows. And that what really matters.

As with all MFT sensors, when in doubt it is better to underexpose, preserve the right exposure in the highlights, and open the shadows in post-processing.

DMC-GX7, 1/500, f/ 2.8, ISO 200 – From RAW

With regards to dynamic range, the GX7 offers some interesting settings that will only affect the JPGs. The first is the i.Dynamic option which, if set to On, will generate a JPG version with the highest detail available in both shadows and highlights. The result is a “flat” picture with less contrast.

DMC-GX7, 1/640, f/ 8/1, ISO 200

The second is an easy option designed for adjusting highlights and shadows on-camera, reducing the need for laborious post-processing later on. By pressing the Fn2 button in Live View mode, you are taken to a series of small graphs which have varying highlight/shadow settings. The default is Standard, but you can also choose Higher Contrast, Lower Contrast, Brighten Shadows, and three Custom graphs for your preferred settings. You can change the curves by either using the touch screen or the aperture/shutter speed dials.

While I don’t think that photographers will spend a lot of time editing their settings during a shoot with this kind of feature, with time it can help customise picture profiles more accurately. For example, you can control the contrast of the vivid profile by slightly decreasing the shadows in situations where there is too much contrast.

As for colours, we found that the GX7 does a very good job of handling colour accuracy. Below are just a few examples of OOC JPGs from the GX7. The only editing performed was the addition of our website’s logo to the images:

DMC-GX7, 1/8000, f/ 22/10, ISO 200

DMC-GX7, 1/250, f/ 2/1, ISO 200
DMC-GX7, 1/250, f/ 2, ISO 200

The only thing I don’t like about the colours on the GX7 (and also the GH3) is the overall cold tint it produces when you use Auto White Balance. This can sometimes produce an undesired magenta tint on skin tones. If you like to use JPGs straight out of the camera, it is better to set WB manually or like our reader Tim said in the comments section, you can adjust the Auto WB by pressing the down arrow when you select it. You can then move the point to a warmer or colder area on the square colour spectrum.

Below, you can browse through some other examples of the GX7’s colour reproduction taken in various situations (sunny, cloudy, indoors).

 

Performance

Fast and furious autofocus…

The GX7 may not be lightning fast like the Olympus OM-D E-M5 in terms of autofocus, but it is pretty darn close. I experimented with focusing on various objects around the room in S-AF mode – some close, some far away, some highly contrasted, some not so much – and 95% of the time, the GX7 locked onto the subject immediately.

Even when my subject was moving like the squirrel below, the success rate of the GX7’s S-AF was quite surprising. Out of all the shots I took, about 50% were useable. Of course, capturing moving objects, especially ones that dart about like squirrels, is never easy on any camera, and it takes experience, reactiveness and a steady hand on the part of the photographer to keep an image perfectly in focus.

DMC-GX7, 1/500, f/ 1.8, ISO 400

Continuous shooting and tracking…

I tried out the continuous shooting and tracking functions on one of the most mobile and unpredictable subjects you can find: my friend’s chipper five-year-old daughter – let’s call her Anna. The task was simple – I asked her to run towards me as fast as she could with one of my teddy bears in her hand. For each series, I placed the focus point on the teddy to see how the GX7 would handle keeping it in focus as she ran.

The first test was performed with High continuous shooting (5 frames per second), continuous AF and tracking activated. Overall, the GX7 did a pretty good job of predicting the elements that should remain in focus for seven of the eight shots. While the focus on the teddy was lost in the second shot due to Anna swinging him side-to-side, the camera was able to recuperate for the fourth shot. Anna herself remains in focus right up until the last two shots. The shots don’t become blurry until Anna gets very close to the camera.

I then decided to disactivate the tracking function to see if there were any notable differences. In this series, the teddy and Anna are in focus for every shot except the last one. (The teddy’s limbs are flailing but the body remains in focus.) Admittedly, in this set, Anna did not come as close to the camera so there was less chance of the C-AF losing its lock on its subjects.

While anything but a scientific lab test, these images show you that the GX7 is more than capable of tracking fast-moving subjects coming towards you in a real-world situation. This means photographing moving children, animals, cars, bikes and even floppy teddies. It is also quite good at keeping objects with unpredictable movements (i.e. the teddy bear moving forwards and side-to-side) in focus, and recuperating when possible.

The continuous shooting function is fast, though not as quick as an Olympus OM-D or Pen. I would have preferred at least 7 fps on a camera like this but 5 has proven enough for most situations. (In actual fact, I sometimes find that an exceedingly rapid frame per second rate can give you too many shots to sort through later on. Sometimes less is more!)

A word about the GX7 shutter… 

Like the Olympus Pen E-P5 before it, the GX7 is one of the first mirrorless cameras to feature 1/8000 of a second mechanical shutter speed. Combined with its Low 125 ISO, you can easily shoot wide open in bright daylight. Below you can see a few OOC JPG examples taken with the M.Zuiko 45mm at its fastest aperture of f/1.8:

The GX7 also has the option of an electronic shutter, which is excellent for remaining discreet but doesn’t come without its share of flaws. First, it only works up to 3200 ISO so using it in extremely dark places may pose a challenge. Second, if you are shooting inside where neon or florescent lighting is used, you may end up with prominent banding across your image (both JPGs and RAW). This happened when I was photographing the children in my class at Halloween – I wasn’t able to shoot in certain areas of the class with the electronic shutter activated because the lighting produced this effect.

Just stick to using it in naturally-lit settings or rooms with incandescent light and you won’t have any issues.

With the electronic shutter activated, banding across the image would occur at certain points in the classroom where I teach due to the artificial lighting.
With the electronic shutter activated, extreme banding across the image would occur at certain points in the classroom where I teach due to the artificial lighting.

On the bright side, the electronic shutter allows you to boost your continuous shooting up to a maximum of 40 frames per second (if you ever need a burst mode that fast!).

Keep your ISO down with internal stabilisation…

The GX7 is the very first Lumix mirrorless to include internal stabilisation. Up until its release, stabilisation was limited to the Lumix lenses which was all fine and dandy as long as you didn’t use M.Zuiko or other non-stabilised third party lenses with your Lumix camera. With the GX7, this problem has disappeared – you can now use any MFT lens with it and have stabilised images.

A few weeks ago, Mathieu and I decided to compare the internal stabilisation of the GX7 to the Pen E-P5. The E-P5 is in possession of the best IS mechanism on the market, the 5-axis stabilisation, so we knew it would be a challenge for the GX7 to keep up.

As it turned out, the IS of the GX7 is extremely good – not at the level of the E-P5 but certainly enough for most situations. At 1/10 of a second, the results from the two cameras are about equal, but from 1/5 of a second onwards, the GX7 begins to show some blurriness. At one second, there is a very clear difference between the two. To see a full comparison, check out the dedicated article!

Video Function

As good as it gets on a compact mirrorless…

At this point I’ll leave you with Mat as he is the video expert here!

I had the chance to bring the GX7 with me on a professional video shoot I did three weeks ago. Since the client required me to travel as light as possible, I decided to bring the GH3 and GX7 with me as they share the same kind of sensor and both record in AVCHD format.

The GX7 of course lacks some features you can find on the GH3, which is the high-end Lumix model for video. The main difference concerns audio. You won’t find a mic input nor a mini-jack output socket for your headphones. The camera has a built-in stereo microphone but for professional use it is not recommended. I have used the GH3 in the past with microphones connected directly and it works well, although a sound guy wouldn’t be to happy about it. In this case, my colleague recorded audio separately.

The GX7 and the GH3 ready to shoot!

We had to shoot a series of interviews so I used two cameras for each person. The settings were exactly the same on both cameras. I chose AVHCD 25p as the GX7 lacks the ALL-I 72mbps codec the GH3 has. I used my Nikkor glass for this. I had the GX7 set for the wider shots with a 17-35mm f/2.8 attached, while the GH3 has the 85mm f/1.4 mounted for close-ups. We were working with natural light inside a tailor shop with a window behind the subjects, so the lighting conditions were a little bit challenging. In the end, I was really glad to see how well the cameras handled the dynamic range.

One thing that surprised me while editing the footage was that the colours produced by the two cameras were slightly different from each other. Of course they shared the same profile picture as well as the same custom white balance. The GH3 had a more magenta hue while the GX7 was greener, something you could not help but notice in the skin tone. A quick colour correction fixed that, but my only guess is that the sensors are probably calibrated differently, which is logical as the GX7 sensor is newer. I’m just surprised not to have found the same thing with stills.

Apart from that, they both deliver the same image quality and this is why the GX7 can work as a great second body to use side-by-side with the GH3.

I didn’t try the autofocus much on video. I used the Lumix 35-100mm for some hand-held shots and every time I focused it was quick and silent.

The GX7 battery ran out at around 5pm; thankfully, the shoot had just finished. We start to record at around 12pm. In comparison, the GH3 battery still showed three full bars!

Below you can watch the final version of the video.

Stop Motion Animation…

Another interesting option with the GX7 (that you won’t find on the GH3) is the stop motion animation feature. Once enabled, the camera allows you to take a series of pictures that you can then merge into a movie file (mp4 format only). You also have the option to create it by reversing the speed (the order of the images taken).

The camera also records both JPG and RAW files, something useful if you prefer to create the movie file manually with your favourite video editing software. When the feature is enabled, each time you take a picture, the screen will show an overlay on the live view. This allows you to see where your object was before and where it will be when you move it.

Below you can watch a short animation called “Pasta Ouverture” we did a couple of weeks ago by helping our friend Iryna for a project during her course. You can also check out our in-depth article where you’ll see how the video was created.

 

Additional Features

Staying social…

The simple presence of WiFi and NFC on digital cameras isn’t enough to make us go “wow” these days. Nearly every new model has it, so more than ever, we are interested in how well the internet connection works, how easy it is to activate, and the degree of control you have over your settings from your smart device.

Strangely, the app you need to connect the camera to your smart device isn’t the same as the one for the GH3. For the GX7, you need the Panasonic Image App, not the Lumix Link App. However, I must say that the app is very well done. If you choose to remotely control the camera, you can access all the main settings on your tablet such as ISO, white balance, and so on. You’ll even find the quick menu with the same options as you’ll find on the camera. You can also record video from the iPad but the images will be stored on the camera SD card.

Controlling the GX7 from our iPad 3

The Wi-fi function on Lumix cameras is very complete. You can playback your pictures and video on a TV screen, send them to your smart device or laptop, and even record them onto devices during still shooting and upload the images directly to a cloud service (Lumix Club only).

The way you connect the camera may vary depending on the task you want to accomplish and not all the options are easy to set at first but Panasonic without a doubt offers the most complete solution for WiFi in the mirroless camera segment.

Focus Peaking…

For a butterfly photographer such as myself, effective focus peaking can make the difference between a sharp and blurry shot in manual mode. I personally love the focus peaking on the GX7. You can choose between High and Low Detect Level and three display colours (light blue, yellow and green). I tend to stick with the default ‘light blue’ as I find it stands out the best. Even more helpful is the magnification box which gives you a closer view of the object you are focusing on. It can be activated and deactivated at any time on-screen with the touch of a finger.

Multiple Exposures…

Though I’ve only used it a few times, I really enjoy the multiple exposure mode on the GX7. Simply go to Mult. Exp. in the menu, click Overlay if you want to start from a photo you’ve already taken or Start if you want to start off fresh, and begin clicking. Each time you take an image, you will see the previous image as well as a semi-transparent Live View of your scene so you can choose where to overlap your images. When you take the second image, the camera will ask if you want to keep it or try again. In total, you can take up to four exposures in a row before the camera compresses the images into one.

Below is a quick example taken with the Lomography Wide Angle lens for Micro Four Thirds.

 HDR

The camera has an HDR function that allows you to take a series of shots in a burst at different exposures and then merge them into a single JPG image. But as with the GH3 before it and many other cameras which include this function, I don’t like the results very much.

DMC-GX7, f/ 8, ISO 200 – HDR merged on camera with 5 different exposures

Actually, the only camera that has impressed me with on-board HDR is the little Sony RX100M2 (see our full review here). As we always say, you will achieve far better results by merging the RAW files with Photoshop or other editing softwares.

Where does the GX7 fail?

Coming from the Duracell Bunny-type battery of the GH3, we were a little disappointed to discover that the battery life of the GX7 is sub-par. If used intensively, it will last you about four hours but no more. The GH3, on the other hand, will keep you going throughout the day and still have some juice to spare. Granted, the GX7 battery is significantly smaller than that of the GH3, but we were hoping for a level of endurance similar to the E-M5 battery, which is about the same size. We’ll definitely be buying an extra battery, or at least keeping a second body on hand for any long outings.

Conclusion

So, who is this camera for?

Our reviews are never about classifying cameras on the spectrum of ‘good’ and ‘bad’ as truly bad cameras don’t really exist in this day in age. Rather, we try to suggest the ideal user for the cameras we review.

In the case of the GX7, we feel that it is a simple yet very complete package which could satisfy advanced amateurs and professional photographers who engage in a wide range of photography, including reportage, street, wedding, portrait and event. With its excellent video performance, it is an especially interesting option for those who also enjoy hybrid photography and video.

Perhaps due to its low-key appearance, it wouldn’t be the first camera you’d look at in a camera store, but it is jam-packed with all the latest and most useful features, and has a body that is so compact that it can neatly fit into your handbag with a small lens attached. Moreover, being a Micro Four Thirds body, there are dozens of high quality lenses that can be used with the system, and many of them will now be stabilised thanks to the GX7’s IS.

At this point you may be asking, “But what about the Olympus OM-D E-M1? Isn’t it supposed to be the highest performer amongst Micro Four Thirds cameras?

Well, yes, it is currently the most advanced model out there, which is why Mathieu plans to swap it with the E-M5 as his primary work camera, but it lacks one thing – the compact and ergonomic nature of the GX7. With the E-M1, you notice that there is a camera in your hands. The GX7 feels like an extension of your body. If the combination of compactness and ergonomics is of very high importance to you, there isn’t any contest. Go with the GX7.

At the moment, Mathieu is seriously thinking of using the GX7 as a second body alongside the OM-D E-M1. The best MFT cameras in one bag? Sounds like a treat.

  • Poor battery life compared to the GH3
  • Electronic shutter does not work in places with certain types of artificial lighting

    I’d say the GX7’s menu layout is more straightforward but both are very easy cameras to use. I thoroughly enjoyed using both. For cycling races, you may find the a6000 advantageous because of its excellent AF capabilities.

    Great site- Thanks Heather- Far easier to read & understand than a lot of other sites.
    I am looking to replace Canon 1100D with a Sony A6000 or Panasonic GX7- Use- Family/ Buildings, landscapes , occasional Cycling ( races) looking for the ‘simplest to use of these two cameras
    would very much welcome your view, thanks

    Hello Heather,
    I recently bought the GX7 to complement the GX1 I already had. One thing that would point out is that the controls on the camera can be confusing for someone relatively new to Lumix cameras. The book does not mention (or I did not see it) that to use burst bracketing in the drive mode Program has to have other settings made first in the set up. You have to turn off HDR first. No big deal but I like the bracketing (from my decades of Leica film cameras) I do like this camera, though. Very good build quality. I have an LX3 and a GF1 (which I will sell) I bought a used L10 with the Vario Elmarit 14-50 which is quite good but heavy.
    Thanks for reading, John

    The GX7’s EVF is very good but smaller than the E-M1 EVF. As for low light, the E-M1 is better if you enable the faster fps option. But the GX7 EVF can be tilted and that is a very nice thing. Are you undecided between the two cameras?

  • Anoop

    Hi Matheiu

    I really love everything about gx7. But my only doubt is. .is the evf of good size compared to em1. EM1 has very good evf and large size as well. How does gx7 fare to it and the low light performance of the evf?

  • Heather

    EVF – I found it quite unobtrusive. It sticks out a little but it would never snag on anything.

    IS – It is true that the IS of the E-P5 produces a far more fluid result. However, if you use Lumix lenses on the GX7, you will be able to rely on the stabilisation of the lens for video.

    Picture settings – Yes, you can customise the auto WB, saturation, sharpness and contrast. There are also a number of picture profiles you can choose from just like on the Olympus.

    Shutter priority – I actually work in Aperture priority most of the time so I cannot quite remember whether the aperture changes before the ISO in shutter priority mode. I believe it is the rear dial that changes the shutter speed when in Shutter priority mode but you’ll want to double check that.

    My advice would be to try the two models at your local camera store to get a feel for them before you make your purchase. As you said, one needs to be cautious when buying such an expensive piece of equipment. Let us know how you get on!

  • Tyler

    @TN: that’s definitely something to think about. I don’t want to go thru the hassle of returning a new camera.

    @Heather: I know the EVF doesn’t increase the size of the body that much, but I worry that it sticks out just enough that it will be snagging on bags or pockets when I am out and about shooting quickly. Has that happened to you in use? Also, I know the codecs on the GX7 are better, but do you think it outweighs the ability to use IS during video? I’m not too shaky, but I feel like it adds a bit of professionalism to have steady shots. My main concerns though are the out of camera jpegs and shutter priority modes. Is there a way to tweak a picture setting on the GX7 to get jpegs that pop more like the Olympus settings do? Also, have you noticed that in shutter priority mode when going from darker to brighter light the camera changes aperture before it changes ISO? I like staying in shutter priority to properly capture the kids based on activity. Also, which of the two dials controls shutter speed when in shutter priority mode? Thanks for the responses, and sorry for more questions. I don’t usually spend this much money so I’m a little cautious.

  • Heather

    I’d say your assessment is about right. While I love them both, I would be pushed to recommend the GX7 over the E-P5 for the simple fact that it has a built-in viewfinder which does not increase the size of the camera body. You also mentioned that you enjoy shooting video – if that’s the case, you’ll find the quality of the video output of the GX7 better than that of the E-P5. I would miss the 5-axis stabilisation of the E-P5, but the IS of the GX7 is very good as well. Finally, let’s not forget about the price. You can find the GX7 for about 100-200 less than the E-P5 these days, though I’m sure once the EM-10 is released, the E-P5’s price will drop as well. Oh, and I should also mention that the silent shutter on the GX7 is a dream to use. :-)

  • T N Args

    Tyler, I don’t know the answer to your question, but I did notice that DPR and other reviewers rate the jpeg output of the GX7 as slightly better than or at least on par with the EP5. To me though, the unresolved and unpredictable blurring of EP5 pictures is too big a concern; some samples don’t show it and some definitely do.

  • Tyler

    I have been on the fence about which camera to buy between the EP5 and GX7 for quite some time now. I found your and Mathieu’s blog a little earlier this year and have enjoyed reading your real-world style reviews and user experiences about cameras. I noticed that there is a lot of love for the EP5 on this site, and for a while I made up my mind that I would be buying the Olympus after the second round of price drops. In that time however, the GX7 has been getting more and more popular, even on this very blog. Now, I am at a total loss about which camera to buy. I don’t have a camera store nearby that has either model, so I cannot personally test both side-by-side.

    I have gathered pros and cons about each camera, and I enjoy the reviews here, so I was wondering if you could set the record straight and tell me if anything I’ve mentioned below seems out of place. The two cameras share many similar specs, but these are some advantages I see to each:

    GX7 pros over EP5: built-in EVF, better value (have seen it new for $750), better video mode, in-camera lens correction, slightly better high iso performance, I am familiar with Panasonic m4/3 cameras/menus, panorama mode, timelapse mode, silent shutter, better looking grip and external controls, and better focus peaking implementation.

    EP5 pros over GX7: more pleasing out of camera jpeg output (I rarely shoot RAW), no protuding EVF means I can (potentially) use my small GF1 case, better IS system, IS during video, dual-mode twin-dial interface looks very useful, better battery life, higher rate burst mode, in shutter speed priority mode the camera tends to change ISO before aperture (as the GX7 reportedly does), slightly better AWB performance, and more customizable.

    I mainly shoot indoor pictures/videos of my young kids where light isn’t necessarily good and I don’t want to post-process all my photos to get the most out of them. Can you help me decide which one is the best for me or potentially, your readership?

  • Heather

    It’s interesting you say that. Keep in mind that I have fairly small hands. This may be why I find it more comfortable to use.

  • Adam

    Unfortunately, I don’t agree with you about the excellent ergonomics.
    The place for the thumb is too small, therefore, the middle sized thumb accidently press on the badly positioned “Display” button.
    Otherwise, excellent camera.

  • Heather

    Since I don’t own a macro lens yet, I tend to switch between the kit lens (14-42mm) and the M.Zuiko 45mm. However, as soon as my bank account allows for it, I’ll be investing in the M.Zuiko 60mm as I feel it’s the best MFT macro out there. You can see my hands-on here if you’d like.

  • Kurt

    Hello Heather,
    Thanks for the comprehensive and well written review. I’m curious to know which lens(es) you will use with the GX-7 to shoot your butterflies?
    Kurt

  • Heather

    We mostly post-process using Lightroom 5. For Fuji raw files, we’ll sometimes turn to Photo Ninja as it handles the files better.

  • http://wwwjacquescuster.com jacques

    hello
    how do you process the RAW files: on the photoshop camera RAW? lightroom? or another program?
    thanks
    JC

  • Mathieu

    You’re right about that Tim, thanks for pointing it out!

  • Tim

    Auto white balance warm up. You state “The only thing I don’t like about the colours on the GX7 (and also the GH3) is the overall cold tint it produces when you use Auto White Balance. This can sometimes produce an undesired magenta tint on skin tones. I wish there were the possibility to choose a warmer rendering when in Auto WB like on Olympus’ MFT cameras. If you like to use JPGs straight out of the camera, it is better to set WB manually.” After reading your article I looked more closely at my pictures and agree that auto wb was too cold. However there is an option To alter the auto wb from the screen where you choose which wb to use. I warmed mine up a touch and feel much happier about the results now.

  • Mathieu

    Hi Ralph, yes I am a left-eye user because I cannot close my right eye. My nose touches the LCD screen often but since I’m used to it with many cameras, it is not a problem for me. I always use the eye-sensor so there’s no risk of having my nose activating something on the touch screen 😉

  • Ralph

    Hallo,

    Mathieu is left-eyed user. How did he like and manage the EVF on the right side? Did his nose compete on touchscreen while using EVF?

    Thank you for the very good review.

    Regards

    Ralph

  • Heather

    I haven’t tried every MFT lens out there (at least, not yet!) but I was happiest using the M.Zuiko 45mm and 12mm on the GX7 as they keep the camera compact, light and portable with zero compromise in terms of image quality. I also used the Lumix 35-100 while photographing a dance performance the other night, and I found them very well-suited to one another. I should have the chance to use the M.Zuiko 17mm and 75mm on it soon so I’ll let you know how that goes as well. :-)

  • Heather

    I’ll give that a try sometime next week. Thanks for the tip!

  • Heather

    Thanks Eric, and so do we! 😉

  • http://blog.ericcote.net Eric

    Good review, Thanks! I love my GX7 :-)

  • T N Args

    oh, and I have a follow-up tip to your comment on ‘banding’ in electronic shutter mode under fluorescent lighting: try setting the GX7 shutter speed to the same as the AC mains frequency in your country.

  • T N Args

    Nice review, thank you for going to all that trouble. Which lenses did you enjoy using the most with the 7? And which lenses do you think are ‘naturals’ for this camera, fitting in with its ethos and modus?

    I ask because…. I am about to make the big jump to mirrorless, which means I am selling up as I cannot afford multiple systems, and the 7 is the one I can’t take my eye from. (Funny, the camera I am selling is also numbered 7. It seems, for me, it is a case of 7 heaven!)
