This Sigma lens is a product of a beautiful aesthetic and very compact. One might find a little heavy for my part it inspires quality. Its focal 18-250 is a real asset. I chose this goal also for its macro functionality. The first images I made are rendered much better than my old Minolta zoom xi 100-300. The internal ultrasonic motor system (HSM) is a marvel of speed and silence. It complements the 18-55 came with my Sony Alpha 33. A reasonable (399.98), I do not regret my purchase. A word also for Amazon for the quality of its services.
