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.
