Canon EF 17-35mm f/2.8L USM Lens
Canon EF 17-35mm f/2.8L USM Lens is one of four new lenses announced by Canon USA at PMA 1996.
Offering the world's shortest zoom focal length at 17mm, the EF 17-35mm f/2.8L USM extends the benefits of its predecessor, the EF 20-35mm f/2.8L USM which has been extremely popular with photojournalists and other documentary photographers.
The new lens provides silent, high-speed autofocus with outstanding optical performance equal, or superior to, similar fixed focal length lenses. The wide focal length of 17mm was achieved by using two aspherical elements that minimize optical aberrations including distortions and flare, while maintaining high image quality throughout its zoom range.
Autofocusing is fast and accurate, covering the full range from 1.5 feet to infinity in 0.4 seconds. This was achieved through internal focusing which also enhances focusing speed, durability and handling. Additionally, the lens provides fast and smooth manual focusing in the AF mode through its built-in, full-time mechanical manual focus override.
Operability is further enhanced by a wide rubber focusing ring and revolving zoom ring. A drop-in filter holder is also provided at the rear and the non-rotating 77mm front lens mount is perfect for circular polarizing filters.
The Canon EF 17-35mm f/2.8L USM Lens will be available in April 1996
