Hi. I usually buy point and shoot digital cameras, but I want to try a more advanced digital. The most important thing for me is that the picture has to look good on paper, and I am also looking for a camera with good optical zoom capabilities (I am SO SICK of only 3x zoom in point and shoots!) I've looked at : Canon S1 IS (10x, but 3.2MP) $400 retail (uses 4xAA) Olympus C-770 Ultra Zoom (10x, 4MP) $600 retail Panasonic DMC-FZ20K (12x, 5MP) $600 retail Which of these (and any others in this range) are the best? I don't want to pay more than $650 for the camera itself. May go a little higher, but not too much. I also have another question. To what extent does the resolution of the picture matter when printed on a 4x6 photo paper? Would there be a huge difference between 3.2MP and 5MP? Thanks in advance!
