The Tamron 70-300mm f/4-5.6 Di LD Macro Autofocus Lens is a compact, light-weight, ultra-tele zoom which covers the 70mm to 300mm telephoto range and produces photographs of exceptional image quality. It is ideal for taking pictures at a distance particularly when the subject is difficult to approach such as in nature and wildlife photography as well as at sporting and theatrical events. The Tamron 70-300mm also excels at portraiture and allows you to isolate the subject from the background for eye-catching, dramatic portraits. This versatile zoom has superb macro capability with a magnification of 1:2 enabling 1/2 life-size close-up shots of flowers, insects, and other objects that normally would require the use of a specially designed macro lens. This new lens is made with the Tamron Di (Digitally Integrated) design which uses an optical system with improved multi-coatings designed to function with Digital SLR Cameras as well as Film SLR Cameras. Tamron also incorporates LD (Low Dispersion) glass in this lens to correct chromatic aberration, resulting in clear, sharp, and beautifully vivid images.
