Tokina AT-X 116 Pro DX 11-16mm f2.8 Lenses (Canon)

The Tokina 11-16mm f/2.8 AT-X 116 Pro DX Autofocus Lens is an ultra wide angle, short zoom range lens specifically designed for use with digital SLR cameras. The slightly shorter zoom range of this lens over the popular and award winning 12-24mm lens makes it possible to maintain optical quality even at wide-open apertures. This lens features a fast constant aperture of f/2.8, and provides a focal length equivalent to 16.5-24mm in 35mm format.

As part of the AT-X line, this lens is designed to provide excellent optical quality, and offers advanced features like the WR (Water Resistant) front element, its One-touch Focus Clutch Mechanism, that allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras and a 9-bladed aperture. The excellent lens for short closeup photography.
