I watched another video from Tony Northrup last night, and he came down strong against gray market gear. He unknowingly bought a gray market lens, and he had trouble getting it repaired. He finally found a shop that cheated and fixed it for him. If you think your item will never need repair, you can save some money, but if it were me, I'd always worry about something going wrong with it.
Interesting, Tony N claims to be THE expert when it comes to all things Photography. There are several ways to tell if it is Gray Market gear. I am very surprised at Tony, maybe I will email him and help him out. What do you think? Should we at UHH help Tony out. Private email me your vote and I'll decide then.
