I have the opportunity to buy a used Sigma 120-300 non os lens and would welcome any feedback from any one who has owned one. This would be primarily for Motorsport photography where I can see the advantage of the zoom being beneficial. I appreciate weight is a factor, is there anything else about the performance of the lens I need to be aware of?
