This is the world’s widest full-coverage fisheye zoom and the only such zoom in Canon’s catalog. The 8–15mm f/4L ($1,500, street) offers 180-degree views on all EOS bodies, and, uniquely, on full-frame EOS models it can produce both circular and full-coverage (corner-to-corner) fisheye images.Canon has taken pains to take this lens cross-platform. Equally at home on full-frame, APS-H, and APS-C EOS bodies, it’s compatible with all Canon bodies going back to the dawn of the autofocus era.
