Samyang 8mm T3.8 VDSLR II UMC Fisheye CS Lens Samyang’s 8mm T3.8 VDSLR II UMC Fish-eye CS is a manual focus fish-eye cine lens, designed for use on DSLRs with APS-C sensors. It has been carefully designed for professional film & video work, with the focus gear ring allowing the use of follow focus systems. The decoupled aperture changes quietly & smoothly via a second gear ring. The T number of 3.8 refers to the actual light transmission, while distance scales are marked on both sides of the lens to allow easy & precise control. This lens features 10 elements in 7 groups including a hybrid aspherical element (H-ASP). This H-ASP element minimises colour aberration to give exceptional image quality & high contrast. Samyang’s Ultra Multi Coating (UMC) technology optimises light transmission to minimise flare & ghosting. A detachable petal-shaped lens hood is supplied.
