I recently purchased a new Tamron 24-70 f/2.8 VC off of eBay from a 3rd party seller, T-Dimension (I'd love to hear about people's experiences with them) that included a 5 year warranty. Based on people's positive experiences with the company and the services they offered, I decided to give them a shot. I just received the lens today and it's awesome, my expectations were exceeded! However, after further examination, I found what I believe is the lens filter thread, or perhaps the base of it, is not completely adhered to the front optical element. If I apply pressure to it, it bends down to touch the glass. Here's a picture of the affected area in case I'm not being clear enough:
While I'm confident in the warranty, since the optical quality of the lens isn't affected, should I be worried about this issue or am I just paranoid? What would you guys do in this situation?
