The EF 8-15mm f/4L Fisheye USM Lens from Canon delivers 180° diagonal angle of view images for all EOS SLR cameras with imaging formats ranging from full-frame to APS-C. When the lens is used with full-frame cameras you can choose between a circular fisheye image or full-frame image by using the zoom.
When used with EOS bodies featuring APS-C or APS-H sensors, the lens produces a more traditional, full frame fisheye view. A zoom-lock mechanism on the lens body allows the range to be limited to the focal length that ensures the best possible full-frame view without unsightly vignetting around the edge. 'C' and 'H' markings can be found next to the zoom operation ring, indicating the wide-angle zoom position where vignette-free shooting is possible with either sensor. For filmmakers and photographers who want the look and feel only possible with extreme wide angle and fisheye photography, the Canon EF 8-15mm f/4L Fisheye USM is a world-class choice.
Circular or full frame Fisheye zoom lens There’s no need to buy two specialist lenses when the EF 8-15mm f/4L Fisheye USM offers, either full frame or circular fisheye images when used with cameras with a 24x36mm (full frame) sensor. For photographers shooting with DSLR’s with a smaller sensor, full frame fisheye images are possible. With a 180 diagonal field of view, capturing the whole scene in a single image has never been easier.
L-series quality The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are highly resistant to dust and moisture.
Fast, quiet auto focus A ring USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive extremely rapid auto focus with near-silent operation. A high-speed CPU and optimised AF algorithms contribute further to AF speed. Full time electronic manual focus override is available without having to switch out of AF mode.
Enhanced image quality with SWC coating Designed for use in digital photography, Canon’s patented Subwavelength structure coating helps minimise the ghosting and flare caused by internal reflections. By eliminating the cause, the coating reduces reflections and helps to deliver crisp, clear images.
Easier lens cleaning The foremost and rearmost lens surfaces are treated with a Fluorine Coating which enables the easier cleaning of the lens surface compared to existing coatings.
