Characterized by its ultra-slim profile, the Fisheye Body Cap 9mm f/8 Lens from OM SYSTEM is a distinctive 18mm equivalent lens designed for Micro Four Thirds mirrorless cameras. As its name implies, this lens is just 0.5″ thick, mimicking the appearance of a body cap for a sleek, low-profile design. Despite its compact size, it incorporates two aspherical elements to ensure sharpness and effectively control distortion. Additionally, a manual focus lever allows you to switch between Deep Focus and Close-Up modes.

Key features include:

– A unique 9mm f/8 fisheye design with an 18mm equivalent focal length and an expansive 140° field of view on Micro Four Thirds cameras.
– Ultra-slim body cap design, measuring just 0.5″ thick.
– Incorporation of two aspherical elements to reduce spherical aberrations and manage distortion, ensuring sharp, clear images.
– A manual focus lever that can be set to Deep Focus for distant subjects or Close-Up mode for subjects as close as 7.9″ away.

Miles ★★★★★

I love how thin this lens is—practically a body cap, which makes it perfect for tossing in a jacket pocket. The fixed f/8 aperture works in bright daylight, and the 180° diagonal view creates wild, wrap-around shots I’d never get from a standard lens.

Lily ★★★★★

The 9mm focal length gives such a dramatic fisheye effect that even my kitchen looks like a funhouse. I love that it's barely thicker than a body cap—perfect for slipping into a pocket for spontaneous shots.

Joseph J. ★★★★★

The body cap design makes this lens so small I almost forget it’s attached, and the built-in lens cap is a clever touch. It’s perfect for those spontaneous shots where you want that dramatic fisheye curve without lugging around a big lens.
