Distinguished by its ultra slim form factor, the Fisheye Body Cap 9mm f/8 Lens from Olympus is a unique 18mm equivalent lens for Micro Four Thirds mirrorless cameras. As its name suggests, the 0.5"-thin lens resembles a camera's body cap for a sleek overall profile. Despite its small size, the lens features a pair of aspherical elements to help achieve notable sharpness and well-controlled distortion, and a manual focus lever permits switching between Deep Focus and Close-Up shooting positions.
