Kompanija Tamron se pohvalila najmanjim i najlakšim širokim zum objektivom u klasi. Kao i velika većina objektiva ovog proizvođača, i Tamron 17-35mm f/2.8-4 Di OSD je namenjen za Canon i Nikon full-frame DSLR fotoaparate. Vrlo je lagan za svoju kategoriju (460g), a po pitanju optike sastoji se od 15 elemenata u 10 grupa, od kojih 4 LD, dok su 2 GM. Elementi su premazani BBAR (Broad-Band Anti-Reflection) premazom, koji efikasno umanjuje odbljeske i efekte ghosting-a, dok je prednji element prekriven fluorom u cilju zaštite od prljanja. Štaviše, kućište objektiva je zaptiveno.
Novina koju uvodi Tamron 17-35 među Tamron objektive, osim blende sa rasponom f/2.8-4.0, jeste AF motor. Iz kompanije o novom Optimized Silent Drive (OSD) motoru govore u superlativu i tvrde da obećava vrhunsku brzinu fokusa i nečujan rad.
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 not only can it 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.

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).
