I just took a look at the specs. It looks like a nice digi cam. 3.2 mega pixs.
One item to make note of when taking pics of your tank.
close-up mode 0.15 - 0.5m (5.9 - 19.7in)
Make sure you dont try to focus on anything closer than 5.9" as it looks like that is the closest the camera can focus on.
Its important to know the limits of the camera and make sure you dont try to go outside of those limits. I have used several differnt models at work and I find most digi cams are excellent as long as you dont try to go outside their limits.
The key is to play and take many many pics. After all pixles are free unlike film and processing.
If you take 20 pics and have 1 or 2 awsome shots then its fine. But if you had a std camera and took 24 pics and only had 1-2 good shots it would not be a happy day.
