Sigma 50-150mm f2.8 OS lens - this lens got dropped a while back unfortunately and it damaged one of the elements - I’ve tried to get pictures of it as best I can. As far as I can tell, it doesn’t affect the images taken with the lens but you might something that I haven’t. It’s been a truly great lens but I’ve gone to mirrorless now. Any questions, just let me know.
