The Samyang 14mm f2.8 ED AS IF UMC Lens Nikon Fit is a super wide-angle
lens designed to work with both full-frame and APS-C sensor cameras. Its
optical construction features 14 elements in 12 groups and combines two
ED plus two Aspherical elements (hybrid and standard). All lens elements
are Ultra Multi-Coated (UMC) with the highest-quality new-generation
antireflective layers. This optical construction as well as state-of-the
art materials allows you to take photos of the highest possible quality.
UMC stands for Ultra Multi Coated, which indicates that the lens has
been covered with multi-layered, anti-reflective coating which minimises
reflections and increases image contrast. Thanks to its maximum f/2.8
aperture the lens ensures great low light performance. This lens is a
manual focus lens and does not autofocus (AF).
