I finally received the Tamron 24-70 2.8 VC that I bought on ebay. The first thing I noticed, right after mounting it on my D750, was the front cap was a bit hard to come off the lens. After checking to see if the zooming and autofocus were working fine, they were but it might be back focussing just a bit, I looked closer at the front lens cap to see if there was something that made it a bit hard in removing from the lens. I found a part of it broken along with the plastic piece around the front lens loose, broken and bent a bit. The eBay "Used" listing didn't say it had any faults, just a short description saying it was used a few days and that "it was in like new and perfect working condition". Other than that, it seems to be working fine but I didn't go out to test it out some more, due to a storm/flood warning here. Would you keep this lens or not?
