I'm a contractor and record all phases of remodel and construction. The Ex-S600 has taken over 12,000 high quality images that I regularly forward to clients. It seems to work very well in all lighting situations and I love the 'best shot' feature. I bought a 10mp EX-Z1050 and don't like it nearly as much. I have a Nikon D-80 but still prefer the shirt pocket version of the EX-S600.
Problems:
Have to be careful in low light.
