Compact digital camera; zoom blur images. what am I doingwrong?
You may be doing nothing wrong, however the camera is either having trouble with the focusing circuitry/lens assembly, or you're not holding the camera still enough, with a solid focusing object (not likely, but happens). I suspect that some aspect of the focusing circuitry (while zoomed) isn't functioning. While that can be a microprocessor problem, it's rare and not likely. Most likely there is debris (dust, sand) in the lens assembly, and needs to be blown out with compressed air. If that doesn't work, you can try to zoom, then hold the camera with the lens facing up, and bump it gently with the palm of the hand, on an area without switches. The focusing ring inside the lens assembly is sometimes stuck, or jammed by debris, and can be freed by compressed air. Bumping the camera tries to reseat the focusing ring, so that it works correctly, from the cpu signals, and focusing detector. If these suggestions don't work, it will have to be serviced. Make sure you get an estimate first- the cost of repair often exceeds replacement cost of a new camera, on sale. Good luck!
