Broaden your world with 12mm lens in full frame The 12mm F2.8 UMC II is a manual focus lens designed for full frame sensor sizes. This portable lens realises various images both in long and short distance shooting. You can control the lens precisely when shooting under various exposure environments including relatively dark or too bright situations. This lens features 12 lenses in 8 groups including 2 glass aspherical lens (ASP), and 3 extra low dispersion lens (ED) to offer high resolution. Also Nano Coating System (NCS) of Samyang Optics is used to optimise the light penetration and minimises flare and ghost. With such optical construction, it has 0.2m of minimum focal length to film subjects in near distance. There are 7 aperture blades designed to be almost as a full circle when aperture is closed which expresses starlike ray clearly and beautifully. The frame of the lens is compact and solid since it is made of high-strength aluminium alloy so you can create trustworthy images. A detachable petal-shaped lens hood minimises flare and ghost by sheltering lens from unnecessary light.
