Sigma's 70-300mm f/4-5.6 APO DG Macro Lens is one of several tele zoom lenses. By incorporating the autofocusing motor into the lens itself, it can now autofocus with all Nikon DSLR cameras (including the D40, D40x, etc.). In addition, with the motor built into the lens, focusing will be quieter and more responsive.

The Sigma 2x EX APO Tele Converter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.

This high magnification zoom lens covers focal lengths from 28mm wide angle to 300mm supertelephoto, and has now been improved with even better close-up capability. You can focus as close as 19.7" (50 cm) at all focal lengths, with an effective magnification ratio of 1:3. This lens also incorporates two Special Low Dispersion Lens (SLD) elements, and four Aspherical elements. This versatile, all-purpose zoom lens can capture a wide range of subjects using its wide angle, ultra-telephoto and close-up capabilities.
