The M.Zuiko 17mm f/1.2 PRO is one of Olympus’ most recent offerings for Micro Four Thirds, and also happens to be the fastest moderate wide-angle AF prime for the system at the time of writing. Its most appealing feature is its fast f/1.2 aperture which is useful for low-light work and environmental portraits.
As with all our most recent reviews, we’ve summarised our thoughts about this new prime in video format below. You’ll also find a bullet point list of our main findings and a series of sample images. Enjoy!

Summary of our findings
- quite hefty due to its metallic weatherproof build and the complexity of its optical design
- a better match for large MFT bodies
- features a sliding focus ring on the barrel that when pulled back, engages manual focus and reveals a distance scale
- also comes with a customisable L-Fn button to which you can assign various functions
- has a useful minimum focus distance of 25cm, making it a good companion for close-up work
- sharpness is already impressive wide open and continues to improve as you stop down (all values up to f/11 are excellent)
- a great companion for low-light work because of the excellent performance at its fastest apertures
- out of focus rendering is very pleasant at f/1.2
- at f/1.2, you can also achieve good subject separation as long as you focus close
- is very prone to flare and ghosting when bright light sources are in or close to the frame
- chromatic aberrations, distortion and vignetting don’t present an issue
- the inner focusing system of the lens is both fast and silent as expected
The M.Zuiko 17mm f/1.2, despite its excellent optical performance, is more of a niche product than any other PRO lens released to date. This is because its fast maximum aperture only brings a tangible benefit to certain kinds of photographers – namely professionals who shoot environmental portraits or who work in poor light conditions on a regular basis. For all other genres that require a moderate wide angle, such as street, documentary, or landscapes, the f/1.2 aperture and the beautiful bokeh that accompanies it is a nice bonus but far from a necessity.
