Tamron’s SP AF 70-200mm f/2.8 zoom lens delivers a multi-featured lens with internal focusing while holding the physical lens dimensions to the minimum. With full-size format SLR cameras, this tele-zoom lens covers the full focal length of 70-200mm, and for DSLR cameras with APS-C sized imagers its focal length is equivalent to 109-310mm (with 1.55X approximation). The lens allows a minimum focusing distance of only 37.4” over the entire zoom range and a maximum macro magnification ratio of 1:3.1 at 200mm.
