I'm not interested in the ZD body, but I just wish the ZD back AND the ZD body were released at the same time. I would consider the ZD back to put on the RZ, but not the ZD camera.
Why did they hype the back and the body, and then only release the body? (not in America, of course).
This is simply the worst marketing I've ever seen. I can't even comprehend what these people are thinking.
They would've sold so many units in North America by now, I'm very sure of that. You know why? Because photographers like to buy lots of crap, and try them out, then possibly put them away in a closet, camera bag, or sell them on ebay.
But that ZD back could've been useful, if it was released 2 years ago.
