The Pentax smc P-DA Fish-Eye 10-17mm ED (IF) lens was designed exclusively for use with digital SLRs, and combines full-frame fisheye (180° diagonal angle of view at a focal length of 10mm) to super wide-angle performance in a single unit.

This lens makes it possible to capture images with an expanded perspective including creative deformation of subjects and sharp pan focus that extends throughout the entire frame.
