Quantaray AF 70-300mm f/4-5.6 LD Tele-Macro Lens for Canon EOS 35mm Film/DSLR Cameras.

This is the definitive lightweight, compact telephoto macro zoom with a maximum magnification ratio of 1:2 at the 300mm setting - ideal for shooting subjects that are difficult to approach such as sporting and theatrical events. The lens also features special effects such as the capability to provide beautifully blurred backgrounds to highlight the main subject in portraiture, or "compression effects" that make the most of the telephoto lens. By switching to macro mode, subjects as close as 0.95m can be shot within the focal range of 180-300mm, for true macro photography. The optical system incorporates an LD (Low Dispersion) lens, resulting in clear sharp images free of chromatic aberration.
