I own this lens for more than two years and have not regretted the purchase. Why this review I write is the fact that I am 04.16.2015 it had the opportunity this week to compare with the legendary white Minolta 80- 200 APO 2.8. Both 99th at the Sony Alpha Both achieve offenblendig the same picture results and continues through the entire zoom range with very good results. Before the Alpha 99 rose to me, I had the Sigma at an Alpha 580 and SLT 77 MK 2 and was with the imaging performance on APS C sensor more than satisfied. Conclusion: My recommendation to buy !!!!!
