Product Description
Telephoto zoom lens with excellent cost performance and optimised for use with digital SLR cameras Capable of
macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It’s the ideal
high performance lens for portraits, sports photography, nature photography, and other types of photography that
frequently use the telephoto range. SLD (Special Low Dispersion) glass We used SLD (Special Low Dispersion)
glass in this lens for excellent correction of chromatic aberration. This also corrects for fluctuation of aberration
due to focusing. The new multi layer lens coating reduces flare and ghosting, a common problem with digital
cameras and also creates an optimum colour balance. Macro shooting with maximum magnification 1:2 The
minimum focusing distance is 1.5 m/59 inches at all zoom settings. It also has a switch for changeover to macro
photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to
1:2. Without changing the distance between camera and subject, you can change the shooting magnification
