Hi - new to the site, but it looks like some great information here, and I've been very impressed with the insight of the reviews.
I'm currently using a Ricoh Caplio R4 - bought it for something small with a decent zoom/wide angle range and I really enjoy it, and have started to carry it with me most times that I go out.
But... in the last few months I've started to really love taking candids of people, mostly when I travel. After taking more than 1000 pics, I've started to realize that the R4 is great for carrying with me, but I need more zoom (the Caplio has 7x), less noise, and better stabilization/focus at the far end of the zoom, which is where I'm taking almost all of my pics of people.
You can see web-res samples of what I've been doing here:
I'm optimistic about the Sony A100 with the anti-shake technology... it seems that very few DSLRs have it. Are there advantages one way or the other to get it in the body or lens (other than the fact that if you use multiple lenses you pay for it multiple times)?
Second, what about lenses? I plan to keep the Ricoh for general purpose pictures, and want the DSLR for telephoto only. I don't do this professionally, and don't want to spend more than I have to, but I would like to get a good lens in the 400+mm range (35mm equivalent). It doesn't need to have huge range, so a 200-400 that's sharp and quick would make me happier than a 50-400 that's not.
