I purchased a new, body only, D7200 a few months ago. From day one I've noticed that all lens attach to the body tightly......almost too tightly? Certainly tighter than my D5200. I researched and found some others having the same comments, some commenting about other models too, or specific lens fitting tightly. I don't recall any saying it affected performance. I don't have any complaints either.......well, maybe one. I've had to blow some dust out of the body twice now.......is there a relation to the tightness issue? IDK. Anyway, opinions on whether this is something to worry about or not? Thanks!
