Sigma Zoom lens, 27 Sep 2011
Purchased to replace previous Sigma lens of similar size. Very pleased to say vastly improved design enabling faster and more accurate manual focussing. The auto zoom and macro settings in this product are far superior to the older model. Price-wise Amazon was once again the most competitive, quick delivery, excellently packaged and we know that we can trust this site.
