I don't know anything about lenses, cameras, or the mechanics of it all, but it sure sounds like a lens problem---something electrical isn't making the connection. I hope you get it fixed! There's nothing stinkier than getting a great new toy and having it not work right, it's so frustrating!
By the way, as I started scrapping last night, trying to catch up on my 365 pages (but I was SO distracted by one cute little girl eating lemons out in Arizona!), I opened iTunes and put it on shuffle. What comes up first??? Pachelbel's Canon! AARGH! I thought of you and laughed, and settled in to some layouts with selective color and slanty shots.
