WaveMotion asked:
With the digital assist the, 10X zoom increases to 50X
What other compact cameras can compare?

Canon S5 has 12x optical zoom…
Now that said – here’s a bit of advise:
Never, ever, ever use digital zoom. Forget about its existence, disable it on all your cameras and pretend it was never there! Then e-mail 10 of your frie…. oh.. no… don’t do that :/
Here is why – digital zoom is not exactly a zoom. It’s what we call cropping. Your camera takes a picture, then crops out the middle part of it (discarding everything around), and then, does the most horrible thing – it enlarges the picture to be as big, as if you took it using full sensor.
Why this is bad?
Because the quick and simple resizing algorithm in the camera will most likely irreparably destroy some of the information in a picture. What you should do instead, if your optical zoom is not enough, take the picture at max zoom level, then crop and if necessary resize at home with your photo editing program. Then you’d keep your original, you’d be able to see what resizing done to the picture and step back if needed, and finally you’ll be able to use some sophisticated resizing programs/algorithms if need be, not the default algorithm in your camera.

You don’t look at the 10X zoom rating. There are lots of camera’s with 10x zoom. You look at the maximum focal length.
For the DMC- TZ3 (there is no DMZ-TZ3) the maximum focal length is 280mm (35mm equivalent).
Another long zoom compact camera is the Kodak v610 which has a maximum focal length of 380mm (35mm equivalent).
HTH
Also, looking at a 5x digital assist is not a good idea. All digital assist does is crop the image. You can do that with the most basic photo editing program (MS Paint).
