The nice thing about your camera is that it supports CF cards. Those are Cheap! Your camera supports the 8mp resolution and if you set the camera to use that resolution, you would get very high quality photos that could be blown up to about any size that you wanted. 512mb is not a lot of space for such a resolution. My camera will do 5.1 megapixel and with a 1 gig storage card I can get over 700 pictures on it. That means that I am using aprox 1.2mb per picture. At full resolution I believe that your camera will use 2.2mb per picture and so you can expect to get aprox 230 pictures stored to your CF card. That gives you a 32 picture/day allowance. Kinda tight. I'd consider a larger card to compliment the one that you have. Or better yet, try this on for size:
Hitachi Microdrive
This baby fits in your CF slot, it's a tiny Hard Drive similar to the one that you see in one of the old iPod mini's. At $80 it's a steal! (that's about half-price) It's 4gb of storage space. It'll store about 1800 pictures! or 259 pix/day at full resolution!!!!!!
Can you tell that I once sold electronics for a living?
My guess is that there will be a lot of buzz on the board today, we could hit another milestone today or tommorrow!
