call me a liar, ok. (geez, hope the title fairy doesn't see that one. Seriously.)
Two weeks ago I was on my way to a weekend wedding in Washington DC so I took my 1Dx to Canon in Jamesburg, NJ for the recall service.
Just as an aside, amazing how antiquated the desk service is. Very nice tech though. But they hand you a piece of paper to fill in describing the reason for your visit. Ya think they might have an ipad or computer terminal? Also, I had a RRS plate on the bottom. He asked me for an allen wrench. I said I didn't have one so he went in the back and got one.
Anyway, they did the service very quickly and I had the camera shipped back, their expense, in about four days or so. Haven't really had a chance to use it. Also, unless I'm missing it, I don't see any marking in the battery compartment indicating it was done, but I do have the receipt.
Main reason I brought it in is for future resale value, in case potential buyers wanted to know if it was done, though this is probably the least publicized and known recall yet.
