A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.This can help simplify your workflow by eliminating the need to sync and stitch multiple video files. A Sub Wavelength Coating has been applied to individual elements to control lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. With a beautifully engineered folded optical design, the dual high-performance L-series fisheye lenses combine imagery onto a single image sensor delivering impressive results to a single file.Two ultra-low dispersion glass elements noticeably reduce color fringing and chromatic aberrations for high clarity and color fidelity.Both ends produce dramatic, creatively distorted imagery. with a 180-degree angle of view that enables you to create circular fisheye images, as well as shots with full-frame coverage. Zoom allows you to change from a circular 180° fisheye look to a rectangular image.Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range.Unique fisheye zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 12.8-24mm equivalent focal length range.Additionally, this lens is weather-sealed and has a protective fluorine coating on the exposed elements for use in trying environmental conditions.
The optical design incorporates two ultra-low dispersion glass elements to limit chromatic aberrations and color fringing for high clarity and color accuracy, and a Sub Wavelength coating has also been applied to control flare and ghosting for greater contrast.īalancing the refined optics, this 8-15mm f/4 also sports a ring-type USM mechanism to enable quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Capable of producing both circular and rectangular fisheye effects, this lens is characterized by its notable distortion and rounded image quality along with an immense 180° angle of view at the 8mm position. Specialized and versatile, the EF 8-15mm f/4L Fisheye USM is a Canon L-series lens offering flexibility to a conventionally niche lens type. Canon EF 8-15mm f/4L Fisheye USM Overview
