Sigma 70-300mm F4-5.6 DG macro lens for Nikon
and optimized for use with digital SLR cameras.
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.
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.
Macro shooting with maximum magnification 1:2
It is capable of macro photography with a 1:2 maximum close-up magnification at the 300mm focal length. 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 and a minimum focusing distance of 95cm (37.4 inches).
Without changing the distance between the camera and subject, you can change the shooting magnification.
