Product Description

A unique design amongst telephoto zoom lenses. The EF 70-300mm f/4.5-5.6 DO IS USM incorporates a Diffractive Optical (DO) element that delivers compact size low weight and superb image quality Features Three-layer Diffractive Optical (DO) element Just 9.99cm in length Image Stabilizer High speed AF with manual focus override Circular diaphragm for pleasing bokeh Zoom ring lock A unique approach to telephoto zoom design. Packed with technologyWith its multi-layer Diffractive Optical (DO) element Image Stabilization (IS) and Ultra-Sonic Motor (USM) technologies the EF 70-300mm f/4.5-5.6 DO IS USM is a celebration of precision lens design.Diffractive Optical (DO) opticsThe EF 70-300mm f/4.5-5.6 DO IS USM incorporates a Diffractive Optical (DO) element which reduces the physical size of the lens while preserving image quality. The DO element combines the characteristics of fluorite and UD elements into one piece of glass. The result is high contrast and sharpness as well as tight control over chromatic aberration.Image StabilizerThe EF 70-300mm f/4.5-5.6 DO IS USM features a three stop Image Stabilizer (IS) making this an ideal lens for handheld work. Shutter speeds up to three stops slower than normal can be used with no perceptible increase in image blur. Major movement in a particular direction is automatically interpreted as panning and IS is turned off in this plane.Ultrasonic focusingA ring-type ultrasonic motor drives autofocus extremely quickly and in near silence. Excellent holding torque ensures the point of focus is reached accurately without overshooting.Pleasing background blurA virtually circular aperture diaphragm which is controlled electromagnetically gives out-of-focus regions a softer more even feel and lets in-focus subjects stand out against a blurred background.Integrated into the EOS systemThe AF drive pattern of the lens is tailored to specifically match that of the latest EOS range extracting maximum benefit from the lensandrsquo; speed advantage. The lens ensures optimal flash metering by passing distance information back to a compatible EOS cameraand#039;s E-TTL II flash system.In harmony with the environmentIn keeping with Canonandrsquo;s stringent environmental policy only lead-free glass is used in the lensandrsquo; optics.FeaturesZoom TypeZoom Lens
