Lens Overview — Rokinon 7.5mm f/3.5
Key Features — Rokinon 7.5mm f/3.5
7.5mm Fisheye Prime: Fixed focal length delivers the characteristic ultra-wide, curved distortion of fisheye optics on Micro Four Thirds cameras.
f/3.5 Maximum Aperture: Provides reasonable light-gathering for a fisheye prime, allowing use in moderately low-light conditions.
Micro Four Thirds Mount: Natively compatible with MFT mirrorless cameras from Olympus, Panasonic, and other MFT system manufacturers.
Manual Focus Only: Fully manual focus design with no autofocus, suited to photographers who prefer deliberate control over their shots.
197g Compact Build: Lightweight construction keeps the overall kit small and portable, pairing well with compact MFT mirrorless bodies.
No Filter Thread: The front element has no filter thread, so standard screw-on filters cannot be attached directly to this lens.

Description — Rokinon 7.5mm f/3.5
The Rokinon 7.5mm f/3.5 Fisheye is a prime lens in the wide angle category, designed exclusively for the Micro Four Thirds mirrorless camera system. With a fixed focal length of 7.5mm and a maximum aperture of f/3.5, it delivers the characteristic immersive perspective associated with fisheye optics. Focus is entirely manual — there is no autofocus functionality — giving the photographer full control over focus placement. Image stabilization is not present, so steady technique or a supported surface is recommended in lower light.
One of the lens's most practical attributes is its weight of just 197 grams, making it an easy addition to any lightweight mirrorless kit. The lens mount is Micro Four Thirds, and the lens format is confirmed as Micro Four Thirds (MFT). Note that no filter thread size is specified in the product data, so standard screw-on filter use should be verified separately.
Overall, this is a compact, manually operated fisheye prime built for MFT shooters who want a creative wide perspective without adding significant weight to their system.
