APDOO/OTZNO blues - help!

First post - assistance required for delayed action M photography.

 

I need some input from someone who has actually seen or used the APDOO/OTZNO combination with a post-M6 Leica film camera.

 

***Specifically, how are the APDOO and OTZNO units coupled together?***:confused:

 

Thanks in advance.

Hi,

I need some input from someone who has actually seen or used the APDOO/OTZNO combination with a post-M6 Leica film camera.

***Specifically, how are the APDOO and OTZNO units coupled together?***:confused:

You mean OZTNO/14088, the small clock adapter.

 

It is quite easy to use. Just screw the adapter on the delayed action release, and screw then on the M6 release. Where is the problem ? :(

Thanks, Philippe, but I am still confused:( .

 

My understanding of the APDOO and OTZNO units is as follows - please correct me if you think I am wrong:

 

1) Both APDOO and OTZNO units have one set of threads, either male or female;

2) The Leitz shutter release adaptor unit (OTZNO) has a male thread and this easily attaches to the camera's shutter release button's female thread.

3) The Leitz self-timer unit (APDOO) has only a female thread.

4) I see no apparent method of coupling the APDOO to the OTZNO.

 

I have attached images of both the APDOO and OTZNO units. Perhaps I am missing something :eek:. Look forward to any further input. Thanks.

OZTNO is the right code name.

 

Here a picture of this combination on a M2

If you don't have one at hand, it's difficult to figure out, but as soon as you can handle it, it's easy as drinking beer ! :cool:

Hi Luigi,

the internal thread of the APDOO is used only to screw it on the LTMs release button, after you have unscrewed its collar

You don't even have to unscrew the collar on Leica older than IIIb (so on IIIc and up) to use the "bell" release cable (or the APDOO). ;)

Always precise eh, Philippe... :) but I have only 1 IIIc & 1 IIIf.... btw, I have also the DIREKT, really very very old... you surely know what hell it is... ;)

Super stuff, Philippe and Luigi - you have both been very helpful. The APDOO is currently on its way to me (I already have the OZTNO), and I look forward to carrying out your instructions upon its arrival.

 

Sounds like I will be included in my Christmas shots this year, and here's to many more self-portraits thereafter. Again, thanks for your support. :D

 

 

Sota,

Sota,

 

Sota, when you'll have your APDOO, do not forget that the little dented collar acts to "fine tune" the position of the moving part that effectively "presses" the button... you have to make some trial befor finding the correct position... and :) ... I hope your APDOO is complete with its little fine APOOM leather case...

Luigi, thanks for the APDOO fine-tuning information.

 

The APDOO was advertised as "excellent ++", in its original Leitz box, but there was no mention of the APOOM leather case. I will wait until I take receipt of the APDOO - who knows, I might not have to go APOOM-hunting.

 

One last thing re: fine-tuning. Could you please clarify exactly what you mean by "the little dented collar". Are you referring to the knurled ring on the bottom part of the APDOO that comes into contact with the OZTNO?

 

 

Sota :).

Yes, exactly... at the moment I wrote I couldn't remind the term "knurled"...:)

Bongiorno Luigi,

I'm sorry to contradict you, but i don't think this is the best way to adjust the fine tuning of APDOO, then, by turning the collar you also separate it from the body shutter. It should be fixed strongly.

Actually, it is mean of a little screw situated inside (see from the bottom). You may screw or unscrew little by little to have the right length course for your camera. :cool:

Luigi & Philippe,

 

Good news - I have received the APDOO and can report that it attaches very easily to the OZTNO. This coupling is done by engaging the male thread on the central column in the top half of the OZTNO to the female thread of the APDOO :).

 

Note that the male thread on the central column in the top half of the OZTNO cannot be seen when the OZTNO is casually inspected. I discovered it by pure chance after thoroughly digesting Luigi's information.

 

And now the bad news - I have so far been very unsuccessful in calibrating the APDOO so that it releases the M shutter. Adjusting the screw situated at the bottom of the APDOO to the required length appears to be a very delicate operation which calls for infinite patience. I will need to set some time aside to tackle it - if you have any additional helpful information regarding the setting up process please advise accordingly :mad:.

 

Luigi, the APDOO came in a beautiful red Leitz box so I did not get the APOOM :(. Thanks.

 

 

Sota.

I have the same problem with adjusting the depth of the setting by means of the tiny inner screw.I have spent some time on it but without success.Might the spring be weak or broken?Both the APDOO and the OZTNO work well separetly. But will not release the shutter when set up together.

Any suggestions would be appreciateded.I should add that my camera is a newish MP.

Miers, your first task is to ascertain that both APDOO and OZTNO are fully functional.

 

Setting up is a one-off operation that requires the patient, gradual adjustment of the screw at the bottom of the APDOO, until you locate a sweet spot that triggers the shutter. There may be other ways of setting up, but I had no manual and just very basic instructions.

 

Patience is the key.

 

Set some time aside and if you can, avoid any interruptions. I managed to get mine done after two separate 30-minute sessions. It should not have taken so long, but I got impatient and did not maintain strict adherence to the process. Adjustments to the screw should be done in small steps - I recommend 90˚ turns. After each adjustment, set up the combo and see if it fires. Etc., etc.

 

At some point in the process, you will enter the sweet zone, within which the shutter will be fired by the combo. Once you are in the sweet zone, switch to 45˚ turns and continue tweaking until you are happy with your sweet spot.

 

One more thing - for a particular combo, the sweet spot set-up for camera X is not necessarily the sweet spot set-up for camera Y. I noticed my set-up worked for my two MPs but not for my M6.

 

Well, there you go - let us know how you get on.

Exactly. I use this combination with one MP but it doesn't work on the other. I have not yet fiddled enough to see if I can get it to work on both. Kind of a Heath Robinson thing but very effective!

Thank you for your detailed and helpful advice.I am delighted to say I followed your advice and...it worked.! Marvelous!What a splendid little whizz bang!

I have to fione tune a little yet I think but at least I know that everything is fully functional.

The finish on the Apdoo is very fine and matches my black MP beautifully.When this precision item is whizzing away it affirms the satisfaction of using finely made mechanical instruments.

Thank you again.
