Telephoto zoom lenses with excellent cost performance and optimized 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. 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.SLD (Special Low Dispersion) glass in this lens provides excellent correction of chromatic aberration.
New coating reduces Ghost and Flare.
The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom 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. High optical performance is demonstrated throughout the entire zoom range.
