15mm

The EF8–15mm f/4L FISHEYE USM is a fisheye zoom lens for Canon digital single-lens reflex cameras (DSLRs) with an EF lens mount. It delivers 180° diagonal angle of view images for all EOS SLR cameras with imaging formats ranging from full-frame to APS-C, and provides 180° circular fisheye images for full-frame EOS models. Announced by Canon in 2010, it features UD glass for suppression of chromatic aberration and a subwavelength coating for reduced ghosting. It has full-time manual focus for instant switching from AF to Manual operation.
