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, & other types of photography that frequently use the telephoto range. 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 & ghosting, a common problem with digital cameras & also creates an optimum colour balance. 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 & 300mm with a maximum close-up magnification from 1:2.9 to 1:2. Without changing the distance between camera & subject, you can change the shooting magnification.
