The Sigma 70-300 is a 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.
Sigma’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
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.
It is equipped with three pieces of SLD glass for high image quality
This lens has two SLD (Special Low Dispersion) glass elements in the front lens group and one in the rear lens group, the lens has excellent correction of chromatic aberration through the entire zoom range.
Macro shooting with maximum magnification 1:2
High optical performance is demonstrated throughout the entire zoom range. It also has a switch that converts the lens to macro photography at focal lengths between 200mm and 300mm with a minimum focusing distance of 95cm (37.4 inches). In normal mode the minimum focusing distance is 150cm (59.1 inches) at all zoom settings. Maximum magnification between 200mm and 300mm is 1:2.9 to 1:2.
