Verdict

The Rokinon 8mm f/2.8 UMC Fisheye II is a manual focus prime lens designed for APS-C mirrorless cameras, offering a 180° ultra-wide field of view and a 35mm focal length equivalency of 12mm. Its optical construction features 11 elements in 8 groups, including two aspherical and three extra-low dispersion (ED) elements to minimize chromatic aberrations, while the Ultra Multi-Coating (UMC) reduces flare and ghosting. Key advantages include its fast f/2.8 maximum aperture for low-light performance, compact and lightweight build, and excellent center sharpness even when shot wide open. However, common drawbacks include the lack of electronic communication with the camera (manual aperture and focus only), noticeable corner softness, and occasional issues with the lens cap being prone to falling off.
