Overview

The Olympus 9mm F8 Fish-Eye Body Cap Lens is an ultra-compact, fixed-aperture fisheye for Micro Four Thirds, offering a 140° angle of view (18mm equivalent). Optically, it produces strong fisheye distortion that some find creative but others deem unusable; sharpness is mediocre. Build is plastic but sturdy, with a manual focus lever and built-in lens cover. It lacks electrical contacts and auto-exposure. Best suited for casual, experimental shooting where portability and fun outweigh image quality, but not for critical work.
