8X optical zoom is awesome. This is one area where digital shines because an equivalent film camera with 8X telephoto is huge and very heavy. The auto mode is an easy way to take great pictures while you’re trying to learn about the many manual features. In this regard the camera can please people of varying abilities. One set of features you should make time to figure out early are the flash controls. The flash normally washes out pictures easily. Having said this, don’t use a flash unless absolutely necessary. So far it hasn’t had any problems with cold weather.

I’ve read several reviews where people have basically said: “the lithium batteries are too expensive, but they last a really long time.” The fact is they more than pass a rough cost-benefit analysis. But, if you’re not convinced, AA alkaline or rechargables will work.

A word on storage: cameras that use the mini CD’s are too large, heavy and slow. xD picture cards are probably unnecessary because SmartMedia cards are already of negligible size and weight. But be afraid of the industry abandoning SmartMedia. I don’t know enough about Sony’s proprietary stuff to comment, but I instinctively don’t like the idea of proprietary hardware when there are perfectly good alternatives. Downloading from xD or SmartMedia may be a problem if you don’t have a USB port on your computer. I paid $60 for a 128MB SmartMedia card and $20 for a reader that plugs into the computer. You can also upload straight from the camera. The 128MB card holds about 120 - 1984 x 1488 jpeg images.

Downsides: no manual focus, no sound or zoom for movies, deleting pictures is a slow process. The focus has, so far, not been an issue.

Just an additional note to say that I have the 740 version of this camera. It has perfromed w-a-y beyond my expectations and is easy to use. The 740 has 10x zoom and an additional 3x digital zoom.

Of the multi modes preprogrammed, there is also a "my setting" control which allows the user to preconfigure the three most used settings. I use simple 480x640 in the backcountry or around town. In this mode with a 128 card, I get more than 580 pictures! As noted by GN, the lithium batteries seem to last forever. I bought the camera in August 03 and with occassional use I am still using the original batteries (it's 1/8/04). No it is not as tiny or robust as some cameras, but it's not big or fragile either.
