Lens OverviewSamyang 8mm f/3.5

The Samyang 8mm f/3.5 HD Fisheye Lens is a manual-focus prime lens designed for APS-C format DSLR cameras, offering an ultra wide-angle fisheye perspective at a fixed focal length of 8mm. With a maximum aperture of f/3.5, this lens delivers a distinctly immersive field of view well suited to creative photography, architectural shots, action sports, and environmental portraiture. It is available in four mount options — Canon EF, Nikon F, Sony A, and Pentax K — making it accessible to a broad range of DSLR shooters across major camera ecosystems.

As a fully manual lens, all focus adjustments are performed by hand, which gives photographers direct, tactile control over their shots without relying on autofocus systems. There is no image stabilization on board, so users should account for camera steadiness when shooting in lower light. The lens weighs 428g, keeping it reasonably manageable given the fisheye optic design.

No filter thread is listed in the specifications, which is a common characteristic of fisheye lenses due to the extreme curvature of the front element. Overall, this is a purpose-built, mount-versatile fisheye prime for APS-C DSLR photographers seeking a manual, creative wide-angle tool.
