I have a used FG20. It is a beautiful camera but there is a problem. The camera only seems to operate in M90 mode. I have changed the batteries and played with the shutter for almost a week now. I have the instruction manual and have reviewed it. I know that if the batteries were not good, I would not be able to hear a shutter movement apart from the mechanical shutter speed. A second problem is the meter does not move. I see it and the needle hangs at the low end of the scale. Suggestions, ideas, etc. appreciated. I like the feel of this carmera so much I purchased an FG on the spot from the dealer when I went in search of a 50mm AI lens. So, you Nikon folks, can you help. I wanted the mechanical and B shutter speed for some longer exposures. Is this a camera destined to become my desk paper weight?
