Tokina 16mm - 50mm F/2.8 Pro DX Autofocus Zoom Lens for Canon EOS Digital SLR Cameras

Tokina AT-X 165 PRO DX 16-50mm f/2.8 zoom lens exclusively for Digital SLR cameras with APS-C sensors.* The new Tokina AT-X 165 PRO DX makes an excellent standard lens giving the digital photographer the equivalent of a 24-75mm lens in terms of film. From the nature enthusiast to the portrait artist to photojournalist, everyone will be able to appreciate the AT-X 165's bright F/2.8 constant aperture. This wide aperture allows for faster shutter speeds in low-light conditions or a more shallow depth of field for more pleasing portraits. The out of focus background from a wide aperture setting concentrates attention on the subject giving the photo more strength and intimacy. Tokina's exclusive One-touch Focus Clutch Mechanism 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 second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring. The front element of the AT-X 165 PRO DX has a newly formulated WP or "Water Proof" optical coating on the glass. This new coating makes marks such as spots left by water or finger-prints much easier to clean than standard multi-coating.** The rear optical group of the lens contains 1 SD (Super-Low Dispersion) glass element to reduce the number of elements (pieces of glass) in the optical design in order to make the lens more compact, light-weight and faster focusing. * The
Customer Review: Fast Lens for Most Situations
I sold my Canon 17-40 f/4 and Sigma 24-70 f/2.8 and got this lens. It's definitely better than the Sigma and is almost up there with the Canon when it comes to colors and sharpness. I got sick of carrying 2 lenses for different occasions. It's a bit wider than the usual "normal zooms" and is 2.8 all the way which is quite nice. Everyone keeps saying that the CA is large, I don't much care about that. You can correct CA. CA is only perceptible on sunny days when you would stop to f/5.6-f/11 anyways and the CA is small there. It's nice and heavy and I love how it feels. Plus it has a 77mm filter thread (unlike Tamron 17-50 f/2.8 which has the less common 67mm). Overall - I am very happy with it.
