Tamron SP 15-30mm f/2.8 Di VC USD G2 Lens

Model A037 is a new line of ultra-wide-angle zoom lens, which has a separate concept from SP 15-30mm F/2.8 Di VC USD (Model A012), with superb image quality in a small body for high portability . At just 90mm in length and 460g in weight, it is the smallest and lightest in its class. The focal length ranges from an ultra-wide 17mm suitable for professional landscape photography, to a standard 35mm good for snapshot photography.

As for F-stops, the wide-angle end is a large aperture F/2.8, and even at telephoto end is a fast F/4. With Moisture-Resistant Construction and Fluorine Coating, the lens enhances the userÕs photographic experience. For those who would like to try out an ultra-wide-angle zoom lens for the first time, as well as those who are looking for a lens that is easily portable, the A037 is the definitive choice.

The optical construction (15 elements in 10 groups) uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations that are normally seen with ultra-wide-angle zoom lenses. With two properly positioned GM (Glass Molded Aspherical) lenses, distortion and other aberration can be satisfactorily corrected as well.

Being the smallest and lightest in its class and dedicated to high quality imaging, the engineers have paid particular attention to size. The lens has also been carefully designed to allow peripheral point image reproducibility and thereby facilitate a high degree of sharpness and contrast.
