TAMRON AF 55-200mm F/4-5.6 Di II LD Macro for Canon

This is a telephoto zoom for exclusive use on digital SLR cameras that covers the focal length range equivalent to approximately 85-310mm when converted to a 35mm format. The lens will allow owners of digital SLRs fitted with standard zoom lenses to enjoy with ease the professional-looking "pulling" and "compression" effects particular to telephoto lenses. Since the optical system is designed for exclusive use on digital cameras, the image circle is smaller, resulting in a compact package measuring 83.0mm (3.3"), accepting a 52mm standard filter and weighing a mere 295 grams (10.6 oz.). For photographers who bought their digital SLR camera in a kit with a standard zoom lens but are dissatisfied with the telephoto capability of the standard lens, it offers a desirable telephoto zoom range at an affordable price as a second lens. The new tele-zoom will allow these photographers to enjoy the telephoto capabilities that yield dynamic telephoto shots. The lens is ideal for many photographic opportunities including sporting events, scenery and portraiture.
