The G7 is a very nice point & shoot camera. When I say point & shoot, I mean non-SLR. It has a sharp lens, optical image stabilizer from the company that pioneered it, and even a hot shoe so proper flash can be used.
It has a couple of weaknesses though:
1) It is limited by its lens, since it isn't interchangable. You can get thread-in lenses, which give more capability, but optically, they won't give the same quality results as SLR lenses.
2) It uses either an LCD or EVF instead of a real-time, optical image of what you are shooting. This can be a disadvantage for shooting fast action.
However, why would you want to second-guess yourself? You'll give yourself a complex if you wait for everyone else to approve of your choice of camera.
I can only assume you did some research and had good reasons for choosing this camera.
