Tamron
now 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", 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.
