First impressions of the Canon G2:
Bear in mind my old camera is a 3.2MP Kodak DC-3800. The Kodak has some rather serious low light-noise problems.
The G2 is quiet and starts up very quickly. The pictures I've taken so far are all high res jpg that are around 2 megs. Writing to the CF card is very fast. This unit even feels like a camera.
I did install the twain driver as the manual suggested. When I switch the camera to "read" and the USB cable is hooked to the computer a little window will pop up and ask what application I want to open. I select Photoshop-the program opens and I've got a little control panel full of thumbnails of all the pictures I've taken.
If Photoshop was already open, I could just import the images.
I have not taken any .raw images yet.
No problems so far that can't be solved by reading the manual.
