I am about to buy a G3. A friend loaned me his G2 for the day. He gave me some simple insructions on how to operate the G2. I went to the zoo to play with his camera.I soon realized that the camera would focus on the wire screen enclosure and not the Orangutan I was trying to photo. I had called my buddy and he had never had to use this option and was not sure if you could. He had lost his manual. Is it a problem manual focusing with a G3? I am new to digital and only have used manual SLR Nikons(F2as).
