Here's a little spin on the "What dSLR should I get" question that always comes up (no, I'm not asking that particular question, I think I know which one..) The response to "should I get X or Y" overwhelmingly is, pick them up and get the one that feels right in your hands. I have done that in the store with the only cameras available near me, the D40 and XS. Ergonomically, compared to the D40, I think I would choose a compact P&S over the XS I thought the Canon was that bad "feeling". This isn't meant for a comparison of Nikon vs. Canon, or any other brand though..... What my question is, are the higher models in their respective brand similar enough to do this "get the one that feels right"? Theoretically, I have roughly $500 to spend right now and my choices are D40 and XS. What happens then in the future if one was going to upgrade to say a D90 vs. 50D? Is the D90 or D300 for example, built ergonomically similar to the D40 and same with the XS moving to say, a 50D or something (just using models as an example here?) If a D90 is drastically different than a D40 in the ergonomic sense only, or a 50D is drastically different than the Rebel line, that "buy what feels right" is screwed which is why I am asking this. For the record, as I said I have had a D40, friend's D40x, and an XS in my hands looking at them. If and when I was in the market, locally I have available only the D40 though D90 available to look at and hold and only the Rebel XS/XSi available from Canon. My choice thus far would be a Nikon D80 as I hated the Rebel in my hands, but that is also based on holding a D40 and not ever looking at the D80 (D90 is too much $$$). Shot quality wise, I know they are all the same (barring only ISO noise levels) based on the fantastic shots I see here from all camera manufacturers and models. Thus, I do believe in the "see what feels right" concept, but what happens when your first dSLR feels right, but then when ready to upgrade, the upgrade no longer "feels right" and the other manufacturer does "feel right" with the upgraded model? I am thinking mostly of button/wheel placement of which I thought the Rebel line was horrible and the Nikon I had looked at was very accessible and ergonomically good. Just some thoughts I've been wondering as I see the "see what feels right" all the time.
