With this review DpReview concludes the overview of 4 lens reflex 70-200 available for which we have already spoken in the past. This lens announced by Sigma-December 2007 for Canon, Nikon, Sigma, Pentax and Sony has a name that describes in detail this lens, EX identifying the best range of optical Sigma, DG which was designed for digital SLR and, finally , Macro because it is able to focus posts subject to one meter, surpassed only by Tamron, but much better than Canon and Nikon. In hand by a feeling of strength and is definitely better than the Tamron finished, but not reach the levels of Canon and Nikon.

On reflex APS-C, the sharpness is better around 100mm and openness is better between f / 5.6 f / 8, but behaves well opening up, especially with focal shorter. The chromatic aberrations are minimal at 70mm and 200mm increase to where we see the worst result of the four competitors, while distortion is maintained at low levels without creating big problems. A real problem for this lens is the fire which tends to be consistent and in fact in some forums we talk about front-focus to 200mm in the cases of photos macro can be important, while in normal almost non-existent.
