I have a tamron 17-50mm 2.8 non VC that was dropped a couple feet. There is minor visual damage but nothing to the glass just the plastic. The lens is still sharp and focuses without issues on AF. The manually focus works however while rotating the focus ring I get some grinding. I'm actually looking to sell this lens to fund a different lens purchase. Trying to determine if I should get it fixed or sell as is. I've only had it a couple of years so the warranty is still good (not that they will fix it since I dropped it). Thanks, and any opinions on a fair asking price if sold as is.
