The Samyang 8mm f/2.8 UMC Fisheye lens offers an improved optical
construction containing 11 elements in 8 optical groups including 2
aspherical and 3 ED elements for optimum optical performance. The lens
includes a built-in lens hood and the latest generation multilayer
anti-reflection ultra multicoating (UMC) to minimise flare and ghosting.
Fisheye lenses are popular for special effects use where distortion,
exaggerated perspective and extreme depth-of-field are desired. Manual
focus operation only.
