Tamron A037 17-35mm f/2.8-4 Di OSD Lens for Canon This compact ultra-wide-angle zoom lens combines superb image quality with outstanding portability and is the lightest and smallest size in its class. The 17-35mm f2.8-4 Di OSD uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations. And with two GM (Glass Moulded Aspherical) lenses it not only provides the sharpness and contrast demanded by high-end lenses, it also handles peripheral point image reproducibility. The lens resists 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 - enjoy the background blurring effect when shooting full open aperture and close-up with this ultra-wide-angle zoom. The A037 also has a circular aperture that gives you beautiful circular bokeh.
