Sigma 70-300mm f/4-5.6 APO DG Macro Lens for Canon EOS Cameras

Description

Sigma's 70-300mm f/4-5.6 APO-M DG Macro Lens is one of several telae-macro zoom lenses. It is a compact Apochromatic telae-macro zoom lens incorporating two Special Low Dispersion glass elements in the front lens group, plus one Special Low Dispersion glass element in the rear lens group, to minimise chromatic aberration.

This telae-macro zoom lens is capable of focusing down to 1:2 (half life-size) reproduction ratio at 300mm focal length. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm. The lens materials used in this product are lead and arsenic free ecological glass.

The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best colour balance while cutting down on ghosting caused by reflections from the digital image sensor.

Features

• Macro photography with a 1:2 maximum close-up magnification at the 300mm focal length
• 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
