>...it is more profitable to make pro-sumers "move up" to FX...
I've wondered how well this works, perhaps thinking too much about my own equipment. I own 11 lenses, and seven of them are DX lenses. So, moving to FX for me would be almost like buying into a new system. If I were going to do that (I plan to stay DX), I would certainly consider moving to a Canon system as a reasonable alternative. I'm not saying I wouldn't stick with Nikon in such a move; rather, that I'd look at all alternatives, because a move to FX for me would be not just getting a new camera but also giving up most of the lenses I now use. How many other DX users are in a similar situation?
I'm not complaining about my lenses. I like them and they work well for just about everything I want to photograph. So, I want to keep my lens collection, which means, sticking with DX.
I suppose Nikon DX users might have some brand loyalty, but my point is that for many of them, moving to FX isn't just buying a new camera.
