Lens OverviewRokinon 8mm f/3.5

The Rokinon 8mm f/3.5 Fisheye is a manual-focus prime lens designed for APS-C camera systems, available in a broad range of mounts including Canon EF, Nikon F, Sony A, Sony E, and Micro Four Thirds. As a fisheye prime in the wide-angle category, it delivers the characteristic immersive, heavily curved perspective that makes fisheye lenses a popular choice for creative photography, action sports, skateboarding, architecture, and environmental portraiture. With a maximum aperture of f/3.5, the lens offers a reasonable amount of light-gathering capability for a fisheye optic, making it usable in moderately low-light environments.

The lens is manual focus only, with no autofocus or image stabilization, meaning photographers will need to handle focus adjustments themselves — a common characteristic of budget-friendly fisheye lenses. At 428g, it carries a moderate weight that should balance reasonably well on most DSLR bodies. The lens has no filter thread, which is typical for a front-element design of this type.

Its compatibility across five major lens mounts makes it a versatile option for shooters across multiple camera systems who want to explore the fisheye focal length without committing to a system-specific optic.
