An image of a previously patented Canon EF 11-24mm f/4L ultra-wide angle zoom lens has been leaked online. The rumored EF 11-24 f/4L may have shown up on kakaku.com for a short period of time.
If true the EF 11-24mm f/4L lens will provide a focal range between 11mm and 24mm, and feature a constant maximum aperture of f/4. After the announcement of the EF 16-35mm f/4L IS lens, the rumor mill also in talks of Canon is working on an f/2.8 ultra wide angle zoom as possible candidate.
The EF 11-24mm f/4 ultra wide-angle zoom lens will sure be a wonderful choice for Canon users because in this focal range the only wide-angle zoom lenses to compete the legendary Nikon 14-24mm f/2.8G are the EF 16-35mm f/2.8L II or the EF 8-15 f/4L Fisheye.
