The AF 17-35mm f/2.8-4 (D) is a large-aperture, super-wide angle zoom lens with high image quality, optimized for both film and digital SLR cameras. The equivalent focal length with a digital SLR camera is 25.5-52.5mm.
This lens is constructed using aspherical elements and AD glass to ensure highly descriptive performance. These optics minimize distortion at the widest angle of view 17mm, and they produce beautiful images at the largest aperture.
The super-wide angle of view, ideal for capturing the extensiveness of a scene, is suited for landscape and architecture/interior photography.
