Tamron AF 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens for Canon Digital SLR Cameras.
Tamron offers a lightweight, compact, high-image-quality telephoto zoom lens with macro capability of 1:2 that can be used with digital cameras. This new lens is a Di type lens using an optical system with improved multi-coating designed to function with digital SLR cameras as well as film cameras.
With this 70-300mm telephoto zoom lens, flipping a macro switch in the focal length range of 180mm to 300mm obtains a maximum magnification ratio of 1:2 at a minimum focus distance as short as 37.4 inch, enabling close-up shots of flowers, insects, and other objects that normally require the use of a specially designed macro lens. Moreover, this is a zoom lens that casually offers the distant capture and foreshortening effect pleasures of the 300mm ultra-telephoto world. 1 – 2 Macro Magnification Ratio at f=300mm MFD 0.95m Filter Diameter – 62 Weight – 435 gram (15.3 ounces) Diameter x Length – 3.0 x 4.6 inch (76.6mm x 116.5mm) Accessory Lens hood.
