>>I don't understand the focusing system. Is it true that the viewfinder does not show the image in or out of focus, and you have to rely on the distance scale on the LCD readout on top of the camera? Can someone explain briefly how the hell this works? Isn't not being able to confirm focus visually a rather large disadvantage?<<
Doug:
In auto focus mode the distance scale is shown in the viewfinder, e.g., 45 mm lens shows:
0.5, 0.7, 1, 1.5, 2, 3, 5, Inf (meters)
If you have locked focus on something shown in the focus frame, an indicator will either be under one of the numbers in the scale or between two of them.
I found it relatively easy to tell if I had focused on what I had intended, and my first roll thru the camera had everything focused the way I had wanted.
Rangefinders can't show the focus plane in the viewfinder because the lens is not included in the path, as it is with an SLR.
In manual focus mode the distance is shown in the display on top of the camera. However, I wouldn't buy the G2 if manual focus was what I wanted to do.
I spent 45 min to an hour testing the focus system and most of the other functions in the camera store before I decided to buy. If you can rent one, that's even better.
Hope this helps.
