About this item

The Advent of an ideal Ultra Wide-angle zoom lens , well balanced in all aspects...with its superb image quality, compact size and excellant operational ease, this ultra wide-angle zoom lens lets you enjoy dynamic image composition by exaggerating your main subject against a wide background. Create fscinating wide-angle images!

"DI (Digitally Integrated Design) is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of Digital SLR Cameras as well as film cameras. Tamaron's new Ultra Wide-angle zoom lens starts at 17mm when used with a conventional 35mm SLR camera. When mounted on an APS-size Digital SLR Camera, it provides a focal length coverage equivalent to a 28-55mm, covering the desirable wide-angle to standard range.

With its Maximum Magnification Ratio of 1:5.4 at the 35mm setting, this Ultra Wide-angle zoom enables you to take a close-up of a large flower . The M.O.D of only 30cm (11.8") throughout the zoom range lets you get close to the subject so that you can enjoy creative image composition by emphasizing and exaggerating your main subject against a wide background.

Tamron's 17-35mm DI features a maximum open aperture of F/2.8 at the 17mm setting, providing you with the advantage of shooting in dimly-lit conditions and helping to prevent camera shake that leads to blurred subjects. The fast f/2.8 aperture also contributes to a professional look with a beautifull blurred effect in the background : even at wide-angle where depth-of-field is commonly deeper.

Tamron's 17-35mm DI uses 3 aspherical elements , effectively minimizing various abberations. By using Hybrid Aspherical lens elements, the number of elements in this lens is reduced since even one aspherical element can compensate for the same abberations as it would take several spherical elements to do. The end result is both high image quality and compactness in this new wltra wide-angle zoom lens.

Tamron's 17-35mm DI features an LD (low dispertion) lens, which is made of special glass materials that have low dispertion indices to confine dispertion of spectra, a cause of chromatic abberations, to the absolute minimum, and provides sharp and clear images even at the corners.
