With Tamron's F/2.8 telephoto zoom lens, you can master the expression of real depth by creating soft-focus backgrounds to emphasize the crisp, clean lines of your subjects, or take advantage of fast shutter speeds to catch action at a distance. This high-performance fast lens gives you the mobility you need to capture outstanding telephoto zoom images - majestic scenery, stunning portraits, sports action, and more.
This lens boasts a minimum focus distance of 0.95m over the entire zoom range, the best performance in its class. This makes large-aperture telephoto zoom photography possible over a longer shooting range. The lens also has a maximum magnification ratio of 1:3.1 (at 200mm, with a minimum focus distance of 0.95m), enabling you to enjoy close-up macro photography of flowers, insects, and other tiny objects.
This zoom lens uses three LD (low dispersion) elements which effectively compensates for chromatic aberrations providing edge-to-edge sharpness and high-contrast image quality with flat-field characteristics over the entire zoom range. Moreover, through the use of "Internal Surface Coatings (i.e., multiple-layer coatings on cemented surfaces of plural elements)" and multiple-layer coatings to prevent reflections from lens surfaces is reduced to the absolute minimum.
