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.\u003cbr\u003e\u003cem\u003e* Among ultra-wide-angle zoom lenses using an F-stop faster than F\/4 for full-frame DSLR cameras.

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).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAF to capture the moment\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCircular Aperture to Produce a Smooth-Edged Bokeh\u003c\/strong\u003e\u003cbr\u003eA 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFluorine Coating for protection and safe cleaning\u003c\/strong\u003e\u003cbr\u003eThe front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant.
