Samyang's 8mm f/3.5 UMC Fish-eye CS II is a manual focus wide-angle fisheye lens. The CS version is designed primarily for DSLR cameras with APS-C sensors. This review looks at the second-generation lens, which has a removable lens hood.
The optical design of the lens utilises 10 lens elements arranged in seven groups, with one hybrid aspherical element. Multi-layered anti-reflection UMC coatings have been applied to suppress ghosting and flare. The removable lens hood attaches via a bayonet mounting.
A cup-shaped plastic lens cap fits over the front element and is held in place with pinch clips. It can only be fitted when the lens hood is in place and, unlike regular lens caps, is too big to fit easily into a pants pocket when it's not in use.
