I'm new to the forum, thank you for having me as a member.
I just got a new 5D and 24-70. Great camera, but a few days out of the box a few small black dots in sharp focus have appeared in my viewfinder. I cleaned off the focusing screen, but alas these particles seem out of reach behind the SI glass (the one with the focusing targets). Dust on the focusing screen is usually blurry anyway. (I know, you've heard it all before.)
Yes, it doesn't affect my shots, but something like this on a new camera out of reach for me to clean is mildly bothersome. B+H will gladly take it back for an exchange. I might luck out. Of course, I could wind up with a viewfinder with more gunk, or something worse. Or, I could drive down to Canon Services in Irvine and have them clean it I'm sure for free I would imagine (maybe calibrate the camera and lens while they are at it). I'll have to ask them if you only get 1 free cleaning under warranty (unless someone knows the answer to that here).
Anyhow, if it was you... (well, if you are the type to be bothered by it
would you exchange it for another while in the dealer's return window or wait it out and bring it to Canon for cleaning.
Many thanks.....
