I make a lot of my camera equipment purchases as well as many of my everyday household purchases from Amazon. My son even gets his razors on Amazon. I am a big fan of getting a wide variety of opinions on a product from actual buyers and then combining that information with my own experiences to make decisions and recommendations to others.
An overwhelming majority of buyers, 15 out of 16, gave this guide a 4 or 5-star rating on Amazon. (Update: 96% of 22 Buyers)
Here are three more choices for the best Canon Powershot G2 guide. They have a good review ratio. If you take just a quick minute to read a few of the reviews for each, you'll find the one that best matches your needs.
The Canon G12 is one of the "Premium Compact" cameras that I've mentioned as the ideal take-along camera in specific situations where you want a full featured camera, that shoots RAW, has a hot shoe flash mount, and still fits in a large pocket.
I wrote a review of the Canon G11 which is the model I've been using for several years. For me, the only drawback with these cameras is the size of the sensors.
The flip-side advantage of having a smaller sensor is good depth of field and the ability to have a 4x, full-retractable lens. No lens cap is needed. The lens is always on and dust never enters the camera body.
Good luck choosing the best Canon Powershot G12 guide for your needs! Have a blast. Shoot your Canon!
