Sigma 15mm f2.8 EX DG Diagonal Fisheye Lens - Canon Fit

This Sigma 15mm Diagonal Fisheye lens for Canon cameras has an angle of view of 180 in the diagonal direction, in addition to minimum shooting distance of 15cm.

The minimum shooting distance of this lens is 15cm (5.9inch) and has a maximum magnification of 1:3:8.  A large depth of field allows you to take close up photography that covers the objects around the subject.

This 15mm lens is equipped with a gelatin filter holder at the end, admitting the use of gelatin filters.

This lens can also be used with Digital SLR cameras. Although as Digital SLR cameras have smaller image sensor size than 35mm film cameras, for that reason the angle view of 180 cannot be accomplished when is use with Digital SLR cameras. Although, it only uses the centre part of the frame, so distortion will be very small. Therefore you can shoot as normal ultra wide angle lens.
