About Sigma 70-300mm f/4-5.6 DG Macro Tele Zoom Lens for Pentax AF Cameras #509109
Telephoto zoom lens 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.
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
