The 70-300mm offers a lightweight and compact zoom lens with macro capability that can now be used with digital cameras. By flipping a macro switch in the focal length range of 180mm to 300mm, a maximum magnification ratio of 1:2 at a minimum focus distance as short as 95cm is obtained, enabling close-up shots of objects that normally require the use of a specially designed macro lens.
Main Features
Internal Surface Coating to Reduce Ghosting and Flare - By employing "Internal Surface Coatings" (i.e., multiple-layer coatings on cemented surfaces of plural elements) and new multiple-layer coating technology on ordinary elements, ghosting and flare due to reflections that occur when light enters through the front element and reflections caused by the imagers themselves are reduced to the absolute minimum. Moreover, upgraded advanced quality control has been implemented to raise the level of resolution performance standards and prevent flare due to aberrations, which has resulted in a high power zoom lens suitable for photography with digital SLR cameras.
Perfect for Use with Both Digital and 35mm Film Cameras - Both lenses can be used on either Digial or 35mm film cameras.
External Design Shared by All Di Lenses - The external design on both lenses uses a metal relief ring with a special process designation on the ring. The result is heightened visibility and a quality design. Additionally, the black coating over the entire lens barrel creates a high-quality, sophisticated look.
