Olympus m zuiko 17mm f 1 8 vs yongnuo yn17mm f 1 7m?

Both are 17mm primes for Micro Four Thirds with autofocus and no stabilisation, and both frame like a 34mm lens on full frame. The difference on paper is the aperture. The Yongnuo YN17mm f/1.7M is a little faster than the Olympus M.Zuiko 17mm f/1.8, so it gives slightly more light and a touch more background blur, about f/3.4 against f/3.6 equivalent.

Both fit the same long list of bodies, from the OM System OM-1 to the Panasonic Lumix G9 II, so the camera you own won't decide it. My pick is the Yongnuo for the extra speed. If you'd rather stay with the maker's own lens, the Olympus is the choice that keeps everything in one brand. For more on Micro Four Thirds, see the mount guide.
