Experience with Paepke Fototechnik (Düsseldorf) Rolleiflex shutter timing issues

Hello everyone,


I would appreciate some first-hand experience regarding Paepke Fototechnik in Düsseldorf, particularly for Rolleiflex shutter work.


My Rolleiflex 3.5F (Synchro-Compur shutter) has recently been serviced by a very experienced Rolleiflex technician in The Netherlands. The camera received a CLA, mechanical inspection and a repair of shutter speeds that were way off.
The slower speeds seem to be stable now, but the shutter speeds are still not within specification.


Measured before service (using a shutter tester), the results are:

• 1s → ~1/0.8
• 1/2 → 1/3.2
• 1/4 → 1/5.78
• 1/8 → 1/9.79
• 1/15 → 1/26.42
• 1/30 → 1/42.89
• 1/60 → 1/130
• 1/125 → 1/277
• 1/250 → 1/280
• 1/500 → 1/425

The 1/60 and 1/125 speeds are more than one stop fast, while 1/500 does not fully reach nominal speed. The technician indicated that he was unable to bring the shutter fully back into tolerance, possibly due to internal wear.

After the service:

• 1s → ~1/0.8
• 1/2 → ~1/3.2
• 1/4 → ~1/5
• 1/8 → ~1/7
• 1/15 → ~1/10
• 1/30 → ~1/40
• 1/60 → ~1/100
• 1/125 → ~1/250
• 1/250 → ~1/300
• 1/500 → ~1/400

Now, I've sent the camera to Paepke in Düsseldorf.


I would appreciate hearing from anyone who has had a Rolleiflex serviced by Paepke, had significant shutter timing deviations corrected successfully, can comment on their current pricing range for shutter overhaul or deeper mechanical work.


I don't think that a complete shutter restoration is needed. I’m simply trying to determine whether this is likely to be a minor adjustment, a full shutter rebuild, or potentially uneconomical.


Many thanks in advance for any insights.

If the speeds are consistent, I'd just write them down and accept the situation as it is. With a few exceptions, the speeds look reasonably good and more importantly, the are fairly nicely spaced so as to allow for a suitable exposure to be set in virtually all situations.

What sort of shutter tester are you using? Measuring shutter times isn't trivial, especially for the fast speeds.

The Synchro-Compur has three adjustment points for 1s to 1/8s, 1/15s to 1/250s and 1/500s. So the problems at 1/2 and 1/125 + 1/60 seem odd. It could be wear on the speed setting cam. This can be fixed by swaging or filing but you have to be dead sure of the measurements.

1/60-1/100 is not more than one stop off but 2/3 off (still bad if accurately measured); nominal speeds at 1/500 are rarely achieved (the tolerance is +/-20%).

I didn't use a tester. The technician did

Well I would trust the diagnosis of the technician and use the measured speeds. Getting a second opinion is nice too.

Are the speeds consistent?
Have you talked to your technician to fix it?#
In another thread I mentioned one amsterdam based tecchie.

Per Post #1,

The shutter times shown as marked speed, after-service measured speed, and difference in stops, are:

1 sec, 1/0.8 sec, + 0.32 stop

1/2 sec, 1/3.2 sec, - 0.68 stop

1/4 sec, 1/5 sec, - 0.32 stop

1/8 sec, 1/7 sec, + 0.19 stop

1/15 sec, 1/10 sec, + 0.68 stop (marked 1/15 sec. is 1/16 sec. per convention)

1/30 sec, 1/40 sec, - 0.32 stop (intended time is 1/32)

1/60 sec, 1/100 sec, - 0.64 stop (intended time 1/64)

1/125 sec, 1/250 sec, - 0.97 stop (intended time 1/128)

1/250 sec, 1/300 sec, - 0.23 stop (intended time 1/256)

1/500 sec, 1/400 sec, + 0.36 stop (intended time 1/512)

I don't know if you're familiar with Mael, located in France?
Website:


He has a thread that he recently updated on LFPF but it's worth reading the whole thread.


He specialises in Rollei's.

I agree with the recommendation of "use what you know, and work with those speeds". It's simple enough and you won't have to go down any further rabbit holes....
