Olympus body-cap fisheye at 9mm for MFT, 140-degree view in a lens barely thicker than a body cap.
The Olympus M.Zuiko 9mm f/8 Fisheye Body Cap Lens is an ultra-slim fisheye optic for Micro Four Thirds that is barely thicker than a standard body cap. The 18mm equivalent fisheye perspective provides a dramatic 140-degree field of view from what is essentially a lens-cap-sized accessory.
The fixed f/8 aperture and snap-focus mechanism provide deep depth of field without a focusing ring — a creative choice that prioritises maximum compactness. The fisheye distortion creates the characteristic curved rendering that bends straight lines dramatically for creative compositions.
Build quality is minimal by design — the lens is intentionally body-cap sized to maximise portability. The aluminium construction is well-finished, and electronic communication with MFT bodies provides EXIF data. The lens adds negligible weight and bulk to any MFT camera.
The Olympus 9mm f/8 Body Cap Fisheye offers the fisheye effect at minimal size and cost for MFT photographers. The body-cap form factor makes it an always-available creative accessory that stays permanently in the camera bag without occupying meaningful space.
