Fisheye lenses allow photographers to shoot spectacular pictures with extreme viewing angles. In combination with a 24x36mm full frame sensor DSLR camera, the Canon EF 8-15mm allows for either full frame or circular fisheye images; with smaller sensors it covers the full frame. Its 180-degree field of view offers exceptional creative capture capabilities. This Canon premium L-series lens features exceptional optical design, quality and durability. The patented SubWavelength Structure Coating (SWC) reduces ghosting effects and flare, while the additional Fluorine coating aids in easy cleaning of the large front element.
