Before I purchased the Optio 330GS I had tried using an early Kodak digital model. It had no zoom, limited functions and drained batteries.
In comparison, this camera is a gem. It has everything the novice photographer could ever need: 3 x digital zoom, several picture modes (including self portrait and 'snow and surf' modes), movie function (upto 30 seconds) and a good autofocus. Furthermore it is easy to use and the software provided is fast and efficient. The LCD screen is clear and is still visible in bright light outdoors.
It is important that if you buy this camera, you also buy a 128mb or 256mb Compact flash card. This allows you to take as many photos as you need. Some critics have also complained that it chews AA batteries. This is true. If you use normal AA alkaline batteries - it will use them up very quickly. However, if you buy some rechargeable NIMH AA's, then they should last for as long as you need. And as they are rechargeable you don't have to keep forking out.
I use this camera mainly to take pictures of surfing (and the ocean) and it functions very well for this purpose. It is also great for taking everyday pictures of your friends and family, as well as self portraits - thus eliminating the need to hand your camera over to a stranger when there is no-one around to take your photo. Good value for money and a quality product.
