11. Summary

Pros:

solid and weather-sealed construction,
very good image quality in the frame centre,
good image quality on the edge of the frame up from the maximum relative aperture,
negligible longitudinal chromatic aberration,
low lateral chromatic aberration,
proper coma correction,
moderate astigmatism,
decent vignetting correction,
sensible performance against bright light,
silent, fast, and accurate autofocus.

Cons:

very high distortion on RAW files,
noticeable vignetting at the 8 mm focal length (but only on RAW files).

It's a fact: launches of such lenses as the Olympus M.Zuiko Digital ED 8-25 mm f/4 PRO interest me personally a lot. I am a fan of landscape photography, I visit many interesting places so mirrorless cameras with smaller sensors and lenses that fit them well are my favourite tools. Because of them my photo bag has become smaller and lighter, my tripod load capacity is reduced so the same instrument can be lighter too. A lens that provides angles of view ranging from over 100 degrees to less than 50 degrees is an ideal partner during photographic trips. In my case it is more than enough for over 95% of photo opportunities and, by and large, I rarely remove it from the camera body. If you add to that a sensible aperture fastness and a possibility of using classic filters with a normal diameter of 72 mm that aren't horribly expensive, you get a practically ideal lens. Of course providing that it doesn't have any slip-ups in the test...

The Olympus M.Zuiko Digital ED 8-25 mm f/4 PRO didn't have any slip-ups and is an instrument which I can personally recommend without any objections. Its price, reaching $1100, is perhaps not that low but lenses with interesting, unique parameters never come cheap. If I, by force, wanted to find any flaw of this one I would mention the fact that I would be happier if the performance of the 8-25 mm model was on par with the performance of its 12-45 mm brother. Of course my expectations are one thing; I am aware that designing and producing an 8-25 mm model is more difficult than the production of the M.Zuiko Digital ED 12-45 mm f/4.0 PRO. Still in the case of the tested lens you get not only a very good sharpness in the frame centre but also practically no slip-ups on edges. At every focal length, up from the maximum relative aperture, you can enjoy good quality images across the frame, a really impressive achievement. Hats off!
