Canon EF 8-15mm f/4L Fisheye USM Lens

The Canon EF 8-15mm f/4L Fisheye USM is a versatile L-series zoom lens that offers both circular and full-frame fisheye perspectives on full-frame Canon EOS DSLRs (and an ultra-wide field of view on APS-C sensor models). Delivering a 180° diagonal field of view at 15mm and a 180° circular image at 8mm, it provides creative distortion for extreme wide-angle, action sports, landscape, and architectural photography. As part of Canon’s flagship L-series, it features weather-sealed construction, advanced optical coatings, and a Ring-type Ultrasonic Motor (USM) for fast, quiet autofocusing with full-time manual override.
