The Canon EF is a beauty. How well have these stood up to the decades? The batteries were supposed to be mercury, but that is manageable.

Both of my EFs work, only in one the battery indicator light no longer lights up. I should be able to do that.

For testing purposes I will sacrifice two Weincells:

Thanks, Tim!

I'm particularly looking forward to your next report on Canon A, that will be a milestone for me.

Thank God I have enough exercise equipment stored away, I wouldn't have room for any more.

But there are paths in Vienna that always lead me to certain shop windows ...

Now that I've reached a certain point in my photography budget, I don't plan on making any further purchases.

I have two Canon A-1s on the bench at the moment. One is beautiful but had electrical issues that I was not able to identify when I had it opened up the first time. The second is interesting in that it's a fire damaged camera that I bought for parts, but then thought that there's a chance I may be able to fix it. After lubrication to loosen it up a bit, I found that I could get the shutter to fire once in a while. I have the parts needed to replace the fire damaged components, so I was hoping for a quick fix. I have not had that much luck yet. I think that the camera has one or more of the metal finger plates that drive the speed dial changes coming loose and giving bad readings.

Maybe this weekend, I'll put some more time into it. Right now, my time is mostly being spent behind a camera instead of poking around the inside of one.

I have looked through my list of projects and marked the projects that I have already worked on here in the forum as GREEN.

I would like to ask you what topics I should continue with. I am also happy to go into GREEN again or go into more detail.

Otherwise, I have


as my next project.

Here is my vote. A fairly obvious and easy choice.
Canon AE-1 and AE-1 Program
Second choice:
Canon EF (camera)
A minor point, and I don't (yet??) have a black beauty, but this should be an easy repair for you.

Thank you for your structured and illustrated reports.

Thanks for your feedback!

I'm starting from scratch with the Canon A series and I'm a bit wary of it, because the mechanics predominate here.

On the other side the electronics should be „clearer“, which, considering the ICs, rightly deserves quotation marks

This also applies to the EF (from the 1970s), where I hope to be able to get the battery control lamp working again.

Tim @88E30M50 is already much further along here, I hope for support!

In any case, I have collected a considerable number of repair candidates and there are very good repair videos and reports on Canon A in the specialist magazines.

Agreed with Canon A!

But first let me try the Nikon EM with winder MD-E and flash SB-E, I hope it won't be quite so difficult.

Then I'll concentrate on the Canon EF and Canon A

The current status of my project list.
  • GREEN: completed
  • ORANGE: partially completed
  • RED: pending


I plan the following order in the processing of the not yet completed projects
  1. All of my Minolta XD-7s work so far. I can therefore only show how to clean the pneumatic mirror shock absorber on a discontinued XD-7 that still works. This is one of the more common problems where the mirror moves only with a delay. We already discussed what it looks like under the hood and how to remove a dent on the top cover.
  2. Canon EF: It remains to be seen whether the battery control is actually easy to repair.
  3. Nikon FG with MD-14: The condition of both devices is still unknown.
  4. Canon AE-1 and AE-1 Program: This will be a larger project. I am currently working on the topic with a focus on digital camera control with a microprocessor.
  5. Nikon MD-12: I don't want to use my mint Nikon FMn for intensive testing again. Maybe I'll get a FE or FM, which we can also look at then.
  6. We have discussed the Minolta XE and its electronic problems using the similarly constructed Leica R3 MOT ELECTRONIC as an example. However, an attempt to repair an XE remains a separate project.
It will continue soon.



What happens next when all projects are completed?

I still have enough of most cameras and winders/motors in stock that we can repeat repairs on or discuss solutions to new problems.

It also offers the opportunity to explore the devices further in terms of technology.

After that, these options are conceiveable:
  1. Examining SLRs that were built after the 1980s and that already have highly integrated electronics. Clarifying what is possible in terms of DIY.
  2. Working with older cameras, where the focus is primarily on the mechanics.
  3. Service for additional lenses.
