This question was previously posted at RFF, but I thought I'd get the input from here as well.
I managed to find a "fully working" QL17 GIII on the 'Bay and while the aperture and shutter seem to work fine, the meter seems a bit odd, at least based on what I'm used to.
Battery light turns on when battery check button is pressed. Camera came with the PX625A, which I understand is too much power for the camera.
When I put the camera to my eye, the needle does not move to changing light conditions. The Olympus 35 RD is the same way (it meters on half press). When I half press, the meter seems to want to move, but sometimes it takes several half presses to change the reading. Other times, the meter reading does not change, even though it's very evidently incorrect.
Although a half press on the Canonet actuates the aperture, it doesn't seem to go to the right one. Going down from 1/500 to 1/8 I can change the shutter speed and keep half pressing the shutter but the aperture doesn't change. As soon as I hit 1/4, the aperture stops down to what looks like f16 (which is correct).
To sum up:
- Meter in viewfinder is "sticky"
- Aperture response is tempermental
I think it would be fine to shoot manually, but anybody have any ideas about the meter? All the testing was done indoors using interior lights. No film in camera. |

When the camera is set to "A", the meter needle should constantly change with different light levels. When the shutter release is pressed half-way, this locks the exposure. The movement you see with the half press is the needle being locked.
With the camera not on "A", the meter should be inoperative. You may have something physically obstructing the needle.
The aperture blades may need to be cleaned. |

The aperture blades seem free enough, however the needle does not move at all to changing light levels. I suspect you may be right about a stuck needle. |

One more question, on a proerly working camera, does the needle move smoothly through the range or does it jerk from reading to reading? |

The needle should move smoothly. Are you sure you are getting power to the meter? |

I tested with a 675 zinc air 1.4V battery that I use in an Olympus 35RD. On the RD it's fine, but I suppose it's about a month old since I broke the air seal. The camera came with a PX625A battery that seemed to be worse for the meter. |
