| Observaciones | 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. |
