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.
