Tamron announces a new ultra-wide-angle zoom lens, the 17-35mm F/2.8-4 Di OSD (Model A037), for 35mm full-frame DSLR cameras. At just 3.5 inches in length and 16.2 oz. in weight, it is the smallest and lightest in its class. The focal length ranges from an ultrawide 17mm that is suitable for professional landscape photography to a standard 35mm perfect for snapshot photography. The wide-angle end is a large aperture F/2.8, and at the telephoto end is a fast F/4. Features include Moisture-Resistant Construction and Fluorine Coating. For those looking to try out an ultra-wide-angle zoom lens for the first time, as well as having a lens that is easily portable, the A037 is the definitive choice. The lens is available in Nikon mount as of September 4, 2018 at the suggested retail price of $599. The launch of the Canon mount model will be announced at a later date.
