I've owned the G12 for over four years and enjoyed it's features so when I checked out the G16 it felt familiar. First, I like the faster lens 5x zoom the pop up flash and better lcd screen. I would have liked a tilt swivel monitor and the timer as a button instead of in the screen menu. Overall I'm very pleased with the camera .
Purchased the Powershot G16 with the waterproof case and it is an outstanding dive camera for the price....Takes great shots both in and out of the water, with WiFi connectability....what more could you ask for..
I have looked for a point and shoot digital camera with low light capability for years. This camera is the best for that I have found or used. It takes great action shots also, which is a plus. I will admit to having a few problems in some situations, but those will be fixed as I learn the camera better and what it can do and what I can do with it.
Not for a moment do I regret my choice in the Canon G16.
This camera is loaded with lots of features. Great pictures. This camera is my camera I put in a housing for my underwater photography enjoyment. With all the settings on it, it is more of an advanced point and shoot camera than most point and shoot. Great pictures.
