If a guy is selling a used camera body and says it has been barely used. How do you know it isnt a grey market camera? It seems that you can make some cash by buying grey market and reselling it as used. Is there any proof that can be given other than the warranty card?
Example:
50D body new : $1099
50D body used : $999
50D grey market :$899-920
I can be totally wrong on this, please correct me if so.
