canon g2/g3 question
I recently came across the canon g2 and g3 cameras and had some questions about them. my first question is do you really need to install the software to get the camera to transfer pics to your computer? i have a fujifilm3800 right now and the camera is picked up by the computer as a usb drive and i can grab pictures without installing any of the software provided. my second question is are these cameras any good at taking low light pictures without flash on? my subject matter will be fish and the 3800 just cant cut it. everyone once in a while ill get lucky and ill get a decent picture out of my many attempts. im hoping that the g2 or g3 will be better because you can set the aperture and the shutter speed as fish move around quite a bit and are hardly ever still. any advice on these two cameras would be much appreciated.
