R3A overlapping exposures??

[luketrash]

On the past two rolls of film I've shot, I have had overlapping exposures once on each roll. In the case of last night, it was a disappointment, since it was two of the better shots on the roll...

I'm curious if any of you have had this happen before, and if there is a generally known cause of it?

Both cases were rolls of Kodak TMY (handrolled onto plastic cartridges that don't bind up.)


Here's what happened last night:

It happened couple of times on my ZI, I find it very annoying, I just hope it wont happen when I get nice shots, btw amazing two images!

 

[Mark Wood]

From what I recall, I think it also happened with the first ZI that Amateur Photographer magazine tested. Are Cosina using Kiev parts...?!?

 

[Nachkebia]

I think it is a design problem and not part related, since it happened to my wife more then to me because she did not remote film properly, still can not figure out why and when it happenes.

I've had this happen on my R2 and R3a. It seems that if I wind it too fast. I have the same problem. It also happens more often with the trigger winder.

So you mean it happens when you wind it fast? thats nice thing to know, thanks!

Well it's 'good to know' that I'm not the only one, but I still feel sorry for you guys 🙂

Maybe I was getting overzealous with my winding, or maybe I'm not sticking the leader into the takeup spool far enough and it's coming loose? I'll have to investigate further.

luketrash : Once you invastigate please let us know :angel:

The rewind button, on the base-plate, is another prime suspect; if you push it in mid roll it can take part of the next crank action to re-engage the sprocket and so not transporting the film fully.

I get the same problem with my R2a and trigger winder (I only use the thumb winder for 1-2 shots per roll). But only about once in 2-3 36exp rolls. The overlap is exactly the same (around about the middle of each frame). I've been making sure the film is in good and tensioned, also that the trigger winder is screwed in firmly.

It would be interesting to know what Cosina say about this, I'll try and find the address and write to them.

 

[Nachkebia]

Cosina? when you finish your letter, please post it here so we can send it to german quality control mister zeiss 😀

Luketrash -- I just sent you a PM about this. Let me know what you think.

 

[kully]

I sent an email to Robert White to get the email address of Cosina UK - but it turns out they [Robert White] are the importers of Cosina into the UK and that Cosina has no representation in Europe.

The reply goes onto say they have had no Voigtlanders go back for frame slippage issues (although a few for minor VF alignment).

I think I'll be leaving the trigger winder at home this month to see whether that is the cause in my case.

'jlw' - care to share your suggestion?

I have a newly purchased r2a, and I had the same thing happen to me on my last roll of film.

I was cranking the film advance lever pretty hard and fast, so maybe that has something to do with it...

Maybe I should slow down?...

 

[luketrash]

I will need to check at lunchtime, the way I hold the camera naturally. I have a tendency to take most of my shots vertically, so perhaps I'm tapping the rewind button on accident with a thumb or stray finger.

I've had my R2a for about a year now (>100 rolls through it) and consistently wind it very fast (though without a trigger winder) and have never had this happen before. I have noticed that the gap between exposures on the negative is surprisingly variable but I can only compare to an electronic Canon EOS so I'm not sure if this is a side effect of a more mechanical device.

Not sure if it would help anyone but my steps for loading the Bessa are:
1. Insert the film cannister and feed the leader into the take-up spool
2. Without closing the back wind on the film until you see that the top and bottom sprokets are properly aligning with the film holes
3. Close the back and do one full wind (should still be 1 shot short of "S")
4. Use the rewind crank to take up the loose film until you hear a kind of squeek noise that indicates that the film is taut
5. Click off another shot with the lens cap on and advance to "S"

Doing this I've never had a double exposure problem although this could be a camera problem which I've been mercifully spared.

 

[kinok1]

thanks for that. I have not yet used the rewind lever to make sure the film is taut. I will do that from now on.

 

[Nachkebia]

rewind lever to make sure the film is taut

I did not quet got it, can anyone explain this to me please? Thank you

 

[luketrash]

To assure that the film has been loaded correctly, he winds the film backwards with the winding lever to make sure it grabs tight on the takeup spool.

I will try doing this, myself.

It did happen to me on one roll of film when used to own a Bessa R, but its never happened on my R2A (so far).
On seeing the negatives, I thought I may have been a bit sloppy when I loaded the film. When I load a film now, i make sure the film is properly located in the takeup spool, the sprockets are properly located and the film is tight before I close the back.
My father now owns my old Bessa R and hasn't reported any problems to me.
I have found that both the R and the R2A put uneven spacing between the frames.
