Features

TheSigma 8mm f/3.5 EX DGis a spherical fisheye lens that easily captures a full 180 view in all directions, in a circular image. Even the most familiar and mundane of subjects can be portrayed with startlingly fresh new expressions through exaggerated perspectives and unusual distortion effects.

Well suited for academic and technical measurements such as solid angle measurements, cloud cover measurements & virtual reality.

Note:Full circle can only be captured with 35mm format digital SLR and film SLR cameras.

Improvements: This improved version offers a brighter f/3.5 aperture, with a vastly improved minimum focusing distance of 5.3" (13.5 cm) and a maximum magnification of 1:4.6.

Ideal for Scientific Applications: This lens is useful for academic/technical applications such as solid angle measurements, because it provides a quantifiable angle/area relationship. It is widely used in science and industry for cloud cover measurements, weather observation, astronomical studies, agriculture etc.
