Overview

The Olympus M.Zuiko 75mm f/1.8 is a premium telephoto prime for Micro Four Thirds, equivalent to 150mm full-frame. It delivers outstanding sharpness from f/1.8 across the frame, with low distortion (~0.4% pincushion) and well-controlled vignetting. Chromatic aberration is noticeable at wide apertures but minimal stopped down. Build is all-metal, compact, and smooth-focusing, but lacks weather sealing and includes no hood. Autofocus is fast and silent. Best for portrait and still-life shooters seeking top optical quality in a portable package.
