is a pretty good link. Offers quite a bit of information, and some sample JPG's.
I'll also tell you that the camera body is about 40% of the camera's worth. It's your lenses that cost a pretty penny. A good camera with poor lenses is worse off than a poor camera with outstanding lenses. Not all SLR lenses are interchangable, so you also need to be looking at
popularity. It's an unfortunate side-effect, but that's the deal if you want to save money and get a functional camera. You may find that your lenses are expensive, not because they are high-quality, but because no one is buying them.
With all that said, the Canon EOS-350 (Digital Rebel
XT) is a respectable camera. You can find a lot of good quality lenses for $300-500, with a smattering of usable lenses for $100-200. You can also find the $1500-2000 lenses. You can also slap a battery pack on the bottom, so
when your battery cover gets ripped off, you can still use the camera without tape. And if your battery pack's cover gets ripped off, you can very easily find a replacement battery pack. :rotfl:
With your Olympus and Fiji, you'd have to hunt around. Nikon is also fairly popular, so you can find a varied selection of Nikon SLR lenses.
Me personally?
I have a Rebel XT. I've also got about $1500 worth in lenses. I've only used my telephoto lens a little bit, and it was a "cheapo". My wide is a good lens, but I don't use it as much; I usually take several photos, instead of fishing it out of my backpack. My macro and near-zoom (5x) I have used extensively, and they cost the most, as well.
