Samyang 12mm T3.1 ED AS NCS Fisheye VDSLR is a fisheye lens designed for full-frame Canon cameras such as Canon 5D Mark III and Canon 6D. Minimum focusing distance is 0.2 m. A 7-blade diaphragm provides smooth bokeh. Focus and aperture rings have standard 0.8 pitch gears, enabling follow focus use without additional gear rings. De-clicked aperture control supports smooth iris changes during filming. Optical design: 12 elements in 8 groups. Three low-dispersion elements and two aspherical elements provide sharp images with minimal chromatic aberration across the frame at all distances. NCS (nano crystal) coating reduces flare and ghosting and maintains accurate color reproduction. Included: Samyang 12mm T3.1 ED AS NCS Fisheye VDSLR lens, rear cap, front cap, transport pouch.
