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 was 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.
Ease of Use and Compact Size Retained
A 7x magnification power is now available when used with digital SLR cameras. This marks an extension of the intrinsic convenience of digital cameras, which allows photo images to be checked on the spot, and to be processed freely on a personal computer. The lens retains the compact size of the previous model, designed for 35mm film, with all the ease of use of a 28-200mm high power zoom lens. The complete package heightens the pleasure of using digital SLR cameras.
Perfect for Use with Both Digital and 35mm Film Cameras
This lens delivers an ultra-long telephoto zoom range up to a 310mm equivalent on an interchangeable-lens type digital SLR camera, as well as 28mm wide-angle images on a conventional 35mm film SLR camera.
External Design Shared by All Di Lenses
The external design 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.
