Canon EF 8-15mm f/4L Fisheye Zoom
For shooting on the ultra-wide side, Canon has announced the Canon EF 8–15mm/4L Fisheye USM, a rather unique lens in the sense that the wide end of its zoom range produces a circular 180-degree true fisheye image when used on a full-frame DSLR, and a full-field rectangular 180-degree fisheye image when used on a compact (APS-C format) DSLR.
The Canon EF 8–15mm f/4L Fisheye USM lens is expected to be available in January, 2011. The new fisheye zoom is also a Canon 'L'-series lens, which along with pro-quality barrel construction and weatherproofing, contains 14 UD glass elements in 11 groups with Subwavelength and Fluorine coatings to minimize chromatic aberrations, flare and ghosting, and USM motors for quick, responsive focusing. The new zoom also features an AF/M switch to allow easy back-and-forth operation between manual and autofocus.
