Sigma's 70-300mm f4-5.6 DL macro super lens can achieve a magnification ratio of 1:2 (one-half life-size) for macro and telephotography images at its 300mm focal length. As an accessory, you can add a 58mm achromatic close-up lens (not included), and get even closer focusing and reproduction ratios of 1:1 (life size) and still maintain excellent optical quality. The optical materials are made from lead-free and arsenic-free ecological glass. This model is dedicated to Canon AF SLR cameras. Click More Overviews |
