Wide-angle photography just got easier
Creating high quality photos with ease gives you a whole new wide-angle perspective
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.
* Among ultra-wide-angle zoom lenses using an F-stop faster than F/4 for full-frame DSLR cameras. (As of July, 2018: Tamron)

A compact wide-angle zoom lens that's easy to grab and shoot.
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).

AF to capture the moment
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.

Circular Aperture to Produce a Smooth-Edged Bokeh
A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots and avoids rugged aperture geometry.

Fluorine Coating for protection and safe cleaning
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

Electromagnetic diaphragm system compatible with Nikon cameras
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

Compatible with the TAMRON TAP-in Console™
The optional TAP-in Console™ provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF.
