The  NOKTON 21mm  F1.4  Aspherical  VM is  a  large  maximum aperture manual focus  lens  optimized for the  imaging sensors of VM-mount  digital  cameras. The  21mm   focal  length  covers  an angle of 90.3°to create a super dynamic perspective.

Generally the wider a lens gets , the deeper the depth  of focus of the   lens;  however,  with  the   NOKTON  21mm   F1.4   Aspherical VM-mount lens, the extremely large maximum aperture for a super wide-angle lens enables imaging that utilizes “bokeh”(out-of-focus blur). The lens utilizes a floating mechanism to maintain excellent imaging quality throughout the focusing range from close distance to infinity.

Furthermore, the lens features aspherical optics to eliminate distortion and chromatic aberrations in addition to enabling a compact optical design despite the large maximum aperture.

21 mm/1:1.8 Ultron
This  lens  is  specially  designed  for manual  focusing  coupled  precisely  with  the  camera’s  optical  rangefinder system. Compared with a single lens reflex camera finder, the rangefinder focusing system focuses wide angle lenses  with much  more  precision, enabling  the  photographer to use the  shallow  depth  of focus  offered  by the large maximum aperture with peace of mind. The lens couples with the camera’s rangefinder from infinity down to

0.70m (differs depending on the camera) and features a helicoid that enable the lens to focus down to a minimum focus  distance  of 0.50m.  The  feature  really  shows its  strengths when shooting  using  a  camera with  live  view functionality. The included bayonet type rectangular hood  is stylish, effective at shielding stray light and  can  be easily attached to and removed from the lens.
