    • Product Information
    This circular fisheye lens produces circular images with an angle of view of 180° when attached to a full-frame digital or 35mm film SLR camera. It has a maximum aperture of F3.5, a minimum focusing distance of 13.5cm (5.5”) and a maximum magnification of 1:4.6. The special fisheye design allows maximum creative expression. Sigma’s super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. The new lens power layout reduces color aberrations. Providing excellent image quality for digital and film SLR cameras. This lens can be used for the scientific applications such as the solid angle measurements of cloud distribution over the sky, the vegetation distribution of the rain forest canopy, etc., due to the quantifiable angle/area relationship it produces. This lens has a gelatin filter holder at the rear, allowing the use of gelatin filters.

      It’s a much better version than the previous f4 lens. Flare
      control is good. Combined with a Full Frame camera, you
      can see the entire circular view with no other fisheye lens can
      produce. Yes, its’ not a everyday lens but if you need one,
      sigma has it.

      It’s not a problem, just the design issue. The focus ring
      moves during autofocusing which is not good or something I
      don’t like. AF is slow, 2 seconds from closest distance to
      infinity. At USD $650, I expect the lens has internal focus and the focus ring should not move during AF. Not a good design.
