Tokina AT-X 235 20-35mm f/2.8 AF PRO User Reviews
Professional quality lens at a very good price | Rating:
“This lens is very well built. The construction quality is excellent, the focusing is silky smooth, and the photos are razor sharp. I have found a bit of chromatic aberration at full apertures and the lens is a bit softer also when wide open. Just stopping down to 3.5 seems to get rid of the CA and the lens sharpens right up, as well.. This lens is VERY wide, so expect some typical wide-angle distortion. The distortion is very pleasing, not as much as a fish-eye and easily “correctable” using Photoshop if desired. I even created an action for it and it works flawlessly. “ – by A. Rabun

Tokina AT-X 235 20-35mm f/2.8 AF PRO Specifications
The AT-X 235 AF PRO is a wide-angle zoom lens that will produce dynamic images, which are sharp from edge to edge. The fast, constant maximum aperture of f/2.8 makes wide-angle photography, like reportage, effortless in difficult lighting situations such as indoors or at dusk.
Two Pioneering all-glass aspherical lens elements, one front and rear, (F&R aspherical) are employed to eliminate wide-angle spherical astigmatism and correct edge/marginal light rays for superb image quality. Hoya Corporation, the world’s largest optical glass manufacturer, has created a micron-tuned precision molding technique with the accuracy to form aspherical surfaces to the thousandths of a millimeter. These aspherical elements, as well as 11 more of the remaining 13, receive Tokina’s unique multi-coatings to further improve optical performance.
Continuing the tradition of AT-X, this AT-X PRO series lens boasts a solid, all metal construction using duraluminum alloy. Tokina’s Focus Clutch Mechanism allows maximum AF response and sensitivity while focusing manually.
