The Tokina 14-20mm f/2 AT-X PRO DX for Canon is a high quality zoom lens designed specifically for crop-frame Canon EF cameras. Key features include:
- Fast f/2 Aperture Zoom: While most zoom lens apertures top off at f/2.8, the Tokina 14-20mm bests that by a full-stop. This enables stellar low light shooting, as well as providing shallow depth-of-field with a wide-angle zoom.
- Wide Angle Zoom. With a focal length roughly equivalent to 22.4-32mm, the Tokina 14-20 covers a solid middle ground from moderately-wide focal range. This makes it a great option for landscape, event, and street photographers. The image circle is optimized for APS-C and Super35 sized sensors. It does not cover full-frame sensors.
- High Quality Optics. Tokina 14-20mm f/2 AT-X PRO DX utilizes an optical formula that features 13 elements in 11 groups, with two super-low dispersion and two aspherical elements that produce images with high contrast and sharpness. The multi-layer, anti-reflective coating controls lens flare and ghosting for improved contrast when working in harsh lighting conditions.
- Fast Focus. Internal focusing makes for quick AF performance, while the One-Touch Focus Clutch Mechanism switches between AF and MF modes speedily and simply with a simple slide the focusing ring back or forth to change modes.
