I'm looking into buying my first DSLR. I've pretty much settled between the Canon Rebel XS or the Nikon D40. The Rebel XS has pretty much everything I want except spot metering and a good lens. The kit lens seems to get mixed feedback from the various reviews I read. I also hear the while balance has a weakness under incandescent lighting. The D40 has spot metering and a from what I read a good kit lens, but has a three point autofocus (the XS has seven) and the lens lacks image stabilization. Also, unlike the XS, there is no depth of field preview and the lack of a button dedicated to ISO kind of bothers me, too. I guess my main questions are: Does seven point autofocus has that much on a real world advantage over three point? Is depth of field preview that important if I can just check out the final photo on the screen? How easy is the ISO to change on the D40 without a dedicated button? It image stabilization really that important on a 18-55 mm lens? Is spot metering that much of a loss on the XS? If anything, I want a camera that will grow with me for a while before I have to upgrade to something higher end. Something that will get me started but at the same time will not severely limit me when I want to get more advanced. Thanks in advance!
