This has lots of the problems of picture quality that you get with a small sensor, but also is capable of excellent pix in good light. Really!
Don't expect to get great sharpness over the whole zoom range.
The GPS works really great when the camera is on. Although the GPS is still logging when the camera is off - as long as GPS is turned on in the menu - it isn't good at all.
With camera on you can log your movements and later upload the file to GoogleEarth, and you will find that the track is within just fifteen or twenty feet of your actual position. Provided, that is, that you didn't have interference from buildings, trees &etc that skew GPS reception.
The battery has great capacity.
I'm less than thrilled with the design of the case. It isn't nearly as attractive IMO as almost all othe CASIO's.
No big problems. Just upload the firmware updates and enjoy.
