Although I have the Nikkor 200-500, the deal I had with the D500 kind of gave me a Tamron 150-600 G1. The seller mentioned that he had problems with the AF quitting a few times. Removing and re-attaching the lens made it work at all times but he found it very frustrating. So I gave it a trial with my D7200 and so far it focused all the times. I wonder if I could sell it to a friend and keep this friend...
