The 17-35mm F/2.8-4 Di OSD (Model A037) is an ultra-wide-angle zoom lens that combines superb image quality with outstanding portability as the lightest and smallest size in its class.* It uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations. And with two GM (Glass Molded Aspherical) lenses it cannot only provide the sharpness and contrast demanded by high-end lenses, it can also handle peripheral point image reproducibility. Furthermore, it has repeatedly gone through our proprietary ghosting analysis simulation employed to resist backlighting problems from strong light sources to which wide-angle lenses are often subjected. Along with an enhanced high level optical construction, the lens has BBAR (Broad-Band Anti-Reflection) Coating highly effective in reducing reflection and controlling ghosting and flare. The Minimum Object Distance (MOD) for the entire zoom range is a short 0.28m (11 in), so you can still enjoy the background blurring effect when shooting full open aperture and close-up with this ultra-wide-angle zoom. The Model A037 also has a circular aperture that gives you beautiful circular bokeh.

The Model A037 was created to meet the demand for a lightweight, compact lens with high-level optical performance. This single lens covers a full range from ultra-wide angle 17mm for use in professional landscape photography to standard 35mm wide-angle for everyday snapshot photography. Yet it is only 90mm (3.5 in) in length, 83.6mm in diameter, and weighs in at only 460g (16.2 oz).
The AF drive employs a newly developed OSD (Optimized Silent Drive) to ensure silent operation. Upgraded and optimized for even further reduction in drive noise, this drive allows the lens to be used to your heart's content in all situations where silence is required. With its greatly enhanced quality and speed, the new outstanding AF performance and tracking capabilities mean you never have to worry about missing a shot even when focusing on moving subjects.
Using the Model A037 as a set with Tamron’s 35-150mm F/2.8-4 Di VC OSD (Model A043) ultrawide-angle zoom supports an amazingly broad range of shooting styles from landscape and street photography to architecture and portrait photography—and everything in between! What’s more, the lenses have a combined weight of just 1,250g (44.1 oz)*, making them the perfect combo when you want to travel light.

BBAR (Broad-Band Anti-Reflection) Coating BBAR Coating minimizes unwanted ghosting and flare
Circular Aperture A several-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture
Moisture-Resistant Construction Leak-resistant seals throughout the lens barrel help protect your equipment when shooting outdoors
GM (Glass Molded Aspherical) lens elements GM lens elements have a significant impact on minimizing distortion and enhancing the sharpness of the image at its periphery
LD (Low Dispersion) lens elements The characteristic of less of a tendency to separate a ray of light into a rainbow of colors effectively compensates for chromatic and lateral chromatic aberration
Fluorine Coating A highly durable protective fluorine compound that is water- and oil-repellant
OSD (Optimized Silent Drive) DC motor with a great silent operation
