Description — Rokinon 8mm T3.8 Fisheye CS II
The Rokinon 8mm T3.8 Fisheye is a prime lens purpose-built for APS-C sensor cameras, delivering an ultra wide-angle fisheye perspective at a fixed 8mm focal length. The maximum aperture is rated at T3.8, a T-stop measurement that provides consistent exposure values well-suited to video and mixed photo/video workflows. Focus is entirely manual, giving shooters direct, hands-on control without the interference of an autofocus motor.
The lens is offered across four popular mounts — Canon EF, Nikon F, Sony E, and Micro Four Thirds — making it accessible to a wide range of APS-C camera users regardless of their system. Weighing in at 405g, the lens is reasonably portable for a specialty fisheye optic. There is no image stabilization included, so technique and environmental conditions should be factored in during handheld use.
No filter thread is specified, consistent with the design constraints of fisheye front elements. Whether used for creative photography or cinematic video production, this lens provides a distinctive, immersive wide-angle look across multiple camera platforms.
