Hi everyone,
I have a question which deals with the re-calibration of the light-meter on a Canonet.
In a discussion (much) further down, Winfried notes that one can re-calibrate the Canonet's light meter by turning the Galvanometer in its mount. After taking the top off of my Canonet, I cannot, for the life of me, see the screw to which she is referring!
That said, Matt Denton's web page on camera repair notes that in general adjusting the variable resistor on an RF is a possible solution to the problem. Has anyone here used this method for the Canonet? Would anyone specifically warn against it?
PS, sorry about the double post, but the topic below did not bump when I posted to it.
Thanks,
Kent |

If you have a close look at the location where the galvanometer is (it has the variable resistor attached to its back cover) you will see that it is surrounded by - or mounted in - a 'tube' made from die-cast metal with a mat grey surface. The contacts to the hot shoe are mounted on top of this tube which partially is covered by some sticky black tape.
The screw holding the galvanometer in its mount can be seen from the front through the gap between the galvanometer assembly and the frame counter assembly. It is a tiny slotted screw usually secured with some locking paint.
As I mentioned in my post, first you have to set the variable resistor such that you get a linear reading (i.e. 1 f-stop variation for one stop variation of shutter speed). Then set the absolute readings by turning the galvanometer. I found that sometimes it is not easy to turn the galvanometer. Its rear cover is only glued to the body of the galvanometer and often gets loose. |
