Digital Photography Review is probably the best place on the web to get real
info on digital cameras.
If you want a real camera get a Canon EOS 10D

Sadly, all of true HE reflex cameras are still second gen. units. Only
professional working photographer should bother with those. The truth is that
even a low cost Olympus D-360 takes fine pics. A G5 only does better if you
take the time to really learn the camera. For a boat-based unit, a Z1, Sony U30
or a weatherproof U60 or Stylus 400 make a lot more sense.
In the league of cameras costing under 1K, the Z1 offers a lot....10X optical
zoom, ability to shoot good quality video with sound, superior focus and
flash...for under 400.00.
Here's the end of the review...
Based on my testing, I can confidently say that the Minolta DiMAGE Z1 is one
of the best bargains on the market for a long-zoom digicam. I was quite
impressed though, with the way the Z1 combined a novice-friendly design with a
surprising array of advanced features to satisfy more expert users. The price
point, battery life, and shutter lag/cycle time performance are also
impressive. Minolta has a great track record for high-quality lenses on their
digicams, and the Z1's lens is no exception, turning in a better than average
performance for a long-zoom model, with good sharpness and low chromatic
aberration. The Z1's color was also very good, hue-accurate and appropriately
saturated, although I'd like to see it just a slight bit brighter. Contrast is
a little high, but a low-contrast option helps greatly on that score. All in
all, it's hard to find much to fault about the Z1, apart from the somewhat
"Buck Rogers"-styled case, which I don't personally care for. Highly
recommended
