Hi, If the needle doesn’t move in AUTO but the camera shutter speed changes wrt to light then there is something wrong with the needle assembly and you may still use your camera especially outdoors when shutter speeds high enough not to worry about shaking. Have you ever changed your focusing screen? The meter needle can be damaged if you hit around it when the focusing screen is removed. I have 3 FEs, one I bought nearly junk and repaired it but the needle was OK.
