The camera body is really just a support for the lens, the shutter and the film. Any camera, even a pinhole or a plastic toy camera can be used for "serious" photography. The F75 is a fine, modern SLR. One day, once you've gotten your money's worth out of it, you can perhaps get a more expensive body. However, the lens that comes with it as a kit is a slow, relatively cheap consumer zoom lens. Before looking at other accessories, some might upgrade that to say, a 28-105D macro zoom, or a 24-85 AFS zoom. However, seeing as you mention the word "serious", I would really suggest a 50mm 1.8D Nikkor for that camera. Having a lens with a fast aperture opens up a lot of creative possibilities with respect to existing light, and also shallow depth of field. One could argue that a 35mm or an 85mm or whatever lens would be better, but that's a matter of personal preference, and the 50mm 1.8D is money well-spent, since it's so inexpensive while arguably being one of Nikon's very sharpest lenses (and not just Nikon, but anybody's). After I bought my F80, the 50mm was the next thing I got, before filters, flash, tripod, etc.
