Does it cover the whole sensor?

Yes. It is designed for Micro Four Thirds and fills the full rectangular frame, not a circular image.

Is it weather-sealed?

Yes. It is dust-, splash- and freezeproof, which suits rain, snow and underwater housings.

How close can it focus?

0.12m, with 0.20x maximum magnification, so you can get very close to a subject for exaggerated distortion.

Is it worth it over a cheaper fisheye?

The f/1.8 aperture, sealing and sharpness justify it for serious wide and underwater shooters. Casual users may find a slower, cheaper fisheye enough.

The lens, front and rear caps, and a lens hood; check the listing for any extras.

Our take on the OM System 8MM Fisheye Lens

The OM System M.Zuiko ED 8mm f/1.8 Fisheye Pro is a Micro Four Thirds prime that covers the full rectangular sensor with a 180° view, giving a 16mm full-frame-equivalent look with strong fisheye distortion. Its f/1.8 aperture, 0.12m close focus and dust-, splash- and freezeproof sealing set it apart from slower fisheye options. The best new price is $1,099.99 at Amazon as of November 7, 2026, with 3 stores listing it new.

About the OM System 8MM Fisheye Lens

Backscatter - OM System / Olympus M.Zuiko ED 8mm f/1.8 Fisheye Pro

Pairing an expansive 180° angle of view with a fast maximum aperture, the M.Zuiko Digital ED 8mm f/1.8 Fisheye PRO from OM SYSTEM is a Micro Four Thirds system lens offering a 16mm full-frame-equivalent focal length to produce unique perspectives and creative distortions. A sophisticated optical design uses a variety of aspherical, low dispersion, and high-refractive index elements to control a variety of aberrations in order to realize a high degree of sharpness and clarity, and a ZERO lens coating has been applied to improve contrast when working in strong lighting conditions. Additionally, this fisheye lens also sports a Movie & Still Compatible (MSC) AF system that is quick and quiet, and it has a weather-resistant construction to suit working in inclement weather conditions.

• Ultrawide fisheye lens is designed for Micro Four Thirds mirrorless cameras, covers the full area of the rectangular image sensor, and provides a 16mm-equivalent focal length.

• Fisheye design renders a 180° angle of view to produce a distinct visual appeal characterized by dramatic distortion and a creative depiction of space.

• Fast f/1.8 maximum aperture benefits working in difficult and low-light conditions.

• The lens construction integrates one aspherical ED element, three Super ED (extra-low dispersion) elements, one Super HR (high-refractive index) element, and two HR elements into its design to minimize aberrations, distortion, and color fringing while also contributing to overall image sharpness, clarity, and color fidelity.

• A ZERO (Zuiko Extra-Low Reflection Optical) coating has been applied to individual elements to minimize lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions.

• Movie & Still Compatible (MSC) autofocus system benefits both photo and video applications due to its smooth, quiet, and fast performance.

• Dust, splash, and freezeproof construction ensures this lens' performance in inclement conditions and harsh environments.

• Minimum focusing distance of 4.7" pairs with a 0.4x-equivalent maximum magnification for photographing close-up subjects with an exaggerated perspective.
