Lens Overview — Samyang 7.5mm f/3.5

The Samyang 7.5mm f/3.5 UMC Fisheye is a manual focus prime lens designed specifically for the Micro Four Thirds mirrorless camera system. Built for photographers who want to push the boundaries of ultra-wide-angle imaging, this fisheye lens delivers a distinctive curved perspective that makes it well-suited for creative and experimental shooting styles. With a maximum aperture of f/3.5, the lens provides a workable light-gathering capability for a fisheye design in this format.

At just 197g, this is a notably compact and lightweight optic that pairs naturally with the smaller bodies common in the Micro Four Thirds ecosystem, making it an easy addition to any kit without significantly adding bulk or weight. The lens is a true prime, fixed at 7.5mm, and relies entirely on manual focus — meaning photographers will need to engage directly with focus control rather than relying on autofocus assistance. There is no image stabilization on board, so stable shooting technique or a stabilized camera body will be beneficial.

The absence of a filter thread is worth noting for those who regularly use front-mounted filters. Overall, this is a purpose-built fisheye prime for Micro Four Thirds shooters who value a lightweight, manual-focus creative tool.
