While I was climbing down a canyon wall, my Tamron 70-300 VC fell about 2 or 3 feet from my vest and then rolled and bumped about 20 feet down the canyon wall before coming to rest. The shade seems to have taken most of the impact and everything on the lens functions well. I have checked it optically as well as I can (it seems OK) and done a new MFA on the lens. But there is sand under the focus ring and an obvious grinding when it I use the focus ring. Using auto focus does not cause the grinding. Would you:
- Send it to Tamron for inspection and cleaning even though it might cost as much as $300.
- Let a local repairman clean the sand out and maybe inspect it knowing that they probably can't get any needed parts. This will likely be much cheaper and take less time.
- Live with it as it is. Just avoid manual focus.
- Replace it with a new one for about $350 after the rebate.
