Advantages of 12mm F2.8 ED AS NCS FISH-EYE

  1. The lens can handle the 35mm full-frame image size.
  2. With its compact size, the lens is easy to carry and it can produce various images in shooting at a long distance or short distance.
  3. With an optical design in stereoscopic projective mode, the lens can express distortion smoothly, thereby producing stable images.
  4. It compensates for aberrations by using a low dispersion lens and glass aspherical lens and, at the fully opened position, produces a high resolution and a high contrast at the center of the lens as well as around the periphery.
  5. Attachable petal hood for reinforcing the user’s convenience.
  6. High-strength aluminum body with robust durability.
  7. NCS (Nano Coating System) for providing high contrast and the best picture quality with extremely low reflection coating.

This product is designed with its mount so you can easily take photographs by mounting the lens directly onto the camera, without installing an additional adaptor.
