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.
Note! Not suitable for 35mm film SLR cameras.
