Olympus America Inc. M.Zuiko Digital ED 8mm f/1.8 Fisheye Pro Lens for Micro Four Thirds, Black

Ultra-wide fisheye for Micro Four Thirds

The Olympus M.Zuiko Digital ED 8mm f/1.8 Fisheye Pro lens delivers a 180° diagonal angle of view on Micro Four Thirds cameras, equivalent to 16mm in full-frame terms. Its fast f/1.8 maximum aperture enables shallow depth of field and low-light shooting for creative photographers and videographers. Dust, splash and freeze-proof construction rated IP53 ensures reliability in harsh environments down to 14°F.

Fixed focal length and manual focus constraints

The 8mm prime design means framing is controlled by position rather than zoom, and the lens lacks autofocus, requiring manual focus operation. The 7-blade diaphragm produces circular bokeh at f/1.8 but stops down for deeper depth of field when needed. Optical construction uses 17 elements in 15 groups including Super ED and HR glass to control distortion and chromatic aberration across the ultra-wide field.

Replaces slower or narrower fisheye primes

This lens upgrades from f/2.8 or slower fisheye primes that limit low-light capability and creative depth-of-field control. The jump is worth it for shooters who need the fastest available aperture in an 8mm Micro Four Thirds fisheye for astrophotography, underwater or immersive interior work. Buyers who need autofocus or a rectilinear ultra-wide perspective should look elsewhere.
