Tamron AF70-300MM F/4-5.6 Di LD Macro 1:2
The new lens is a Di type lens using an optical system with improved multi-coating.
With this 70-300mm telephoto zoom lens, flipping a macro switch in the focal
length range of 180mm to 300mm obtains a maximum magnification ratio of 1:2
at a minimum focus distance as short as 95cm (37.4"), enabling close-up
shots of flowers, insects, and other objects that normally require the use of
a specially designed macro lens.
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. Additionally, upgraded advanced quality control raises the level of resolution performance standards and prevents flare due to aberrations, resulting in a telephoto zoom lens suitable for photography with interchangeable-lens type digital SLR cameras.
The ultra-long telephoto zoom covering up to 465mm equivalent can be used on
a digital SLR camera, while the wide-end 70mm can be used with a conventional
35mm film SLR camera for portraits and other moderately mid-range shots.
