first, please excuse-me if my english is not very good, i'm french...(but you can correct me: it will be an english lesson as well as a camera repair lesson...)
i have a problem using a flash (canolite or other) with my Canonet: sometime the camera detect the flash mode, and the needle in the viewfinder move accordingly to the distance and sometimes it don't. but even if the flash mode is ok, when i turn the focusing ring, the needle 'dance' from side to side and then don't detect the flash mode anymore (the camera expose as in no flash mode).
i hope what i said is clear, can anybody knows how to fix this? |

If it is the same as the canonet QL 19 you can acces the contacts by taking the bottom plate off.You should see them where the objective barrel meets the bottomplate. One drop of contactspray and moving the focussing ring back and forth cured the problems you descibe on my 19. |

Pay attention!
The contacts are where Lucas describes. But using contact spray might cause a lot of trouble. There are two contact lanes made of some kind of carbon. At one end they are united with a conductive paint which is easily washed away by contact spray. I know what I am writing about. If once cleaned the junction off. Just clean the lanes carefully with a mild solvent like rubbing alcohol.
You might clean the contact sliders with contact spray but do not apply directly. Spray a bit on the edge of a piece of cardboard and rubb it against the slider contacts.
Two other comments:
- the automatic detection of the flash mode only works with the Canolight Flash dedicated for the Canonets
- if you observe the effect of the flash mode on the needle in the viewfinder during daylight you will see a hidden feature of the Canonets: the meter accounts for the daylight and for the flash ! |

thanks to everyone!
i took a look and rub carefully the two lanes, now the contact seems okay. but there is no more contact between the two lanes. i think i have to do a little welding on the right side. |

You can not weld or solder them. They are carbon strips. Try to get a conductive silver powder paint. I have fixed mine with such a paint. Automotive or electronic shops should sell them. Unfortunatly the paint is quite expensive. |

All I can say my 19 is still up and running months after the "treatment" I applied just one drop(let) with a scribe. I run it on a 1.4v hearing aid battery and it makes nice crispy exposures.
As Reiner says, in combination with the canolite D it is a joy to use. |
