The Tokina 14-20mm f/2 AT-X PRO DX for Nikon is a high quality zoom lens designed specifically for crop-frame Nikon DX cameras. Key features include:
21 to 30mm equivalent focal length after sensor crop
Advanced optics for high-quality images
Fast, accurate, and nearly silent autofocus
One-touch focus clutch mechanism
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, and provides shallow depth of field with a wide-angle zoom.
Wide-Angle Zoom. With a focal length roughly equivalent to 21 to 30mm, the Tokina 14-20 covers a range of wide-angle perspectives. This makes it a great option for landscape, event, and street photographers. Its image circle is optimized for APS-C and Super 35 sized sensors. It doesn’t cover full-frame sensors.
High-Quality Optics. The Tokina 14-20mm f/2 AT-X PRO DX’s thirteen-element/eleven-group optical formula uses two super-low dispersion elements and two aspherical elements to produce sharp, high-contrast images. The multi-layer anti-reflective coating controls lens flare and ghosting for improved contrast when working in harsh lighting conditions.
Fast Focusing. This lens’s internal-focusing design makes for quick autofocus performance, while the One-Touch Focus Clutch Mechanism quickly switches between autofocus and manual-focus modes with a simple slide of the focusing ring.
