Hi,this is my 3rd Sigma lens, and it look like Sigma read some of the reviews and got this model even better, trying to over come some minor problem.with great size and weight for 72mm lens, OS that helps in the low light and 200mm picturing, great lens.i gave it 4 and not 5 stars since the zoom is not moving smooth enough in my opinion.enjoy,Motti
