Compact wide-angle prime lens for Micro Four Thirds cameras, offering a bright f/1.8 aperture.
The Olympus M.Zuiko Digital ED 17mm f/1.8 II is the second-generation version of the classic 17mm f/1.8 pancake, adding weather sealing and updated coatings while maintaining the compact form factor and character of the original. The 17mm gives 34mm full-frame equivalent on MFT — a near-normal slightly wide-angle perspective.
17mm focal length (34mm full-frame equivalent), f/1.8 maximum aperture, weather-sealed (IPX1), updated coatings, Micro Four Thirds mount, snap-focus mechanism (manual override via focus ring).
The 17mm f/1.8 II adds weather sealing to the original's already excellent formula, making it practical for outdoor photography in light rain. The snap-focus feature enables instant manual focus override without mode switching — turning the focus ring pulls back a collar to engage manual focus, similar to a rangefinder pull-back mechanism.
Test snap-focus mechanism for smooth operation. Check weather seals. Inspect elements for haze and coating condition. Confirm MFT mount engagement. Test at f/1.8 for sharpness and any field curvature.
