When the original A7 and A7r were released in December 2013, one of the most popular topics was the use of adapted lenses including old SLR, Leica and third party M glass. Adapting M glass to Sony’s full-frame sensor, especially the shorter focal lengths, proved quite challenging. Since Sony’s sensors have a thicker cover glass, the light rays that come from the lens and pass through the cover can produce astigmatism (details on the edges of your image appearing blurred), colour shift and chromatic aberration. The severity of the results depends on the specific lens.

The M.Zuiko 75mm is a telephoto prime lens with a fast aperture of 1.8. It is also ranked as one of the best Micro Four Thirds primes ever, and rightfully so.
