The CCD on the Sony DSC-F717 is 8.8x6.6mm. You need to adjust the f-stop much more to compensate for DOF (I think you'll need to compensate about 3 stops, but I haven't played with the DOF calculator for a F717 in a long time). > I am, however, still quite amazed that the small, cheep SONY (paid > 700 USD for it, used 1 year) performes so well. The DSC-F717 is a great camera. It has more noise than a DSLR due to the tiny little CCD, but on the other hand it is pretty inexpensive. It has less noise than most P&S cameras which use even smaller CCDs. You get a sharp and fast F2-F2.4 lens with a good zoom range (38-190mm equivelent). The UI is pretty good too and I found it easy to use in aperture priority mode. I think that Sony has gone downhill with the F828. Trying to stick another 3 million sensors in that same 8.8x6.6mm space didn't do them any favors. I don't regret selling my DSC-F717 to purchase the *ist D, but I'm glad that I was able to own one (and the earlier F707) for over two years before the *ist D was released. The F7x7 cameras held their value well too and I was able to sell my DSC-F717 for $650us after purchasing it (originally a DSC-F707) 2 weeks after it was released for $800us (plus $100 for a 2 year extended warranty). I was able to upgrade for free because I had an extended warranty and my DSC-F707 was one of the early models with flash issues. alex
