Petri 7S Circle-Eye 45mm f2.8
Petri 7S Circle-Eye 45mm f2.8
Petri 7S Circle-Eye 45mm f2.8 is an economy version of the same model with faster lens.
I bought this camera from eBay. Almost all eBay used cameras from this vintage era need repairs. You just can not believe what you will get from eBay.
Problem: The shutter dial ring does not move all the way. The slow speed not working. Self-timer not working.
The camera has been disassembled and the shutter will come out next.
I had sprayed some chemicals outside for degreasing. I have to be careful because last time when I went back the whole thing was gone. They were blown away by the wind :( Today it is sunny so this will not be the problem unless a squirrel comes and knock it off. I better take it inside and do further cleaning.

Canon Canonet QL19 #2
Here is another Canon Canonet QL19 I bought from eBay for my restoration project.
Problem: The meter is not working. The shutter is not working at slow speeds and self timer is not working.
The meter's indicator was unhooked. I took out the galvanometer and cleaned and adjusted the hair spring and the meter came back to life.
The shutter just needed good cleaning.
The camera has been restored and now in good working condition.

Konica EE-Matic Delux F
Konica EE-Matic Delux F is similar to Wards RF 450 or Konica EE-Matic Delux 2 that I worked on before.
The difference is that it used magi-cube flash and looks kind of neat when you lift up the reflector.
The problem: The focus ring is not moving. The Auto/B ring is not moving properly.
The camera looks very clean so I hope I can get this camera repaired.
The focus was not moving because the grease used on the focusing helicoid got too old and gummy and turned into glue. It took me a while using pluming tools to get the lens out from the helicoids :) I did not damaged the lens.
The shutter blades were running fine but the aperture leaves had oils on them so I decided to take them all apart to do cleaning. The shutter is made by Citizen and it uses only two blades for the shutter but the aperture leaves are 5 just like a serious rangefinder camera like its brother, Konica Auto S2.
It will be fun putting them back tomorrow.
One of the spring battery contact was replaced. It is little bigger than the original but should be O.K. The right side is the old part and the left side is the new contact.
The battery contacts for the meter battery holder is made of stainless steel. The wire could not be soldered. I used a silver electric conducting epoxy. I think this good material was not available back then.
The camera is now working fine and it is for sale and this model and similar is now available from me to repair.

The contacts have battery corrosion. I will clean the posts and may have to replace the spring contacts.

Petri 7S Circle Eye 45mm f1.8
I have finished on Wards RF45 but the battery holder's contact fell inside after I put back everything. I want to cry.
I will not touch that camera again until I have nothing else to do.
Petri 7S
I have started on Petri 7S Circle Eye with 45mm f1.8. Petri 7S comes with the faster lens or with the slower, 45mm f2.8, lens. Both are the same cameras except the lens.
The problem to solve: The shutter. The shutter winds but releases itself. The shutter cleaning should solve the problem.
The shutter is Petri's own design but looks similar to Copal SV shutter.
Cleaning the shutter. The shutter blades and aperture leaves will be cleaned one by one. The slow speed and self timer will be cleaned and lubed.
The shutter is good running condition after it received cleaning.

The finder adjusted and the meter checked but the finder's rangefinder image was too faint. I thought maybe Petri did not do a good job with the finder. I looked at one of the mirrors with two surfaces and it was faded at the middle. No wonder it was too faint :) I took out the mirror from a junked Petri 7S I have and replaced it.
Petri 7S finished and ready for sale.
Petri 7S feature:
* 35mm film rangefinder.
* Made in the 60's.
* Fixed lens. Petri C.C. 45mm f1.8.
* Shutter- Petri made. B, 1 sec to 1/500 sec with self-timer.
