Tamron's lightweight, compact, high-image-quality telephoto zoom lens with macro capability of 1:2 has improved multi-coating for optimised performance with digital SLR cameras as well as film cameras.

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", enabling close-up shots of flowers, insects, and other objects that normally require the use of a specially designed macro lens. Meanwhile, this lens casually offers the distant capture and foreshortening effect pleasures of the 300mm ultra-telephoto world.

*Now available with a built-in motor for Nikon, making it compatible with models such as the D40.
