 I have a Nixe, made by Zeiss Ikon. It is a folding camera, but I can't figure out how to open it.

[egdinger]

 I got it figured out, there is a button hidden under  the letherette.  
 
But now there is a problem with the apature blades, one is not where it should be. It doesn't retract as far as it should, and messes up the shape of the apature.

[Rick]

 that's a problem.  one of the pivot pins on a blade has either broken or (hopefully) just gotten popped out of its little groove.  but getting to it requires a very complete disassembly of the shutter.  what model of shutter is it?

 I don't know what the problem was, but I took off the rear element and just pushed it back into place (probably a bad idea), and it's fine now. But the shutter speeds are another matter...
 
Sorry I thought I had said what it was, it's a

 Usually that works.  How is the shutter behaving  (ie, good at high speeds but hesitant at slow speeds; only fires at one high speed regardless of setting; blades move slowly; etc)?
 
the aperture blades had apparently slipped out of its slot, a

 I may not have got enough fluid on the shafts, What do you use to get it places?
 
It seems to be working decently at higher speeds, but a slow speeds it sticks. And it doesn't want to go to T.

 Well the escapment seems to be working smoothly if I take the cocking ring out. But the cocking ring seems to be sticking, as it won't trip the shutter to close.
 
Also the shutter blades don't close tightly, they leave a small hole in the m

[Rick]

 it sounds like something is out of position, or bent.  the little hole in the center means the blades aren't travelling all the way in the closing direction.
 
it's possible that the resistance to movement could be dirt in the actuating ring a

[egdinger]

 Well I took off the shutter blades, and put them back on. And they are fine now, in relation to the hole. But I have to take them back off and get the ring out too?
 
How does the ring come off?
 
And looking at the cocking ring, and the

[Rick]

 anything a little bit bent will definitely cause a problem.  if you can get them perfectly straight again, you may be able to fix it.
 
if you've gotten to where the blades come off, the actuating ring should be easy - it's the ring that rot

[egdinger]

 I got it fixed. The problem was that the lever that selects if it is T or B was not getting under the rimset dial and causing the part that selects instant or Bulb/Time to get hung up on the lever that closes the shutter.
 
And my slow speeds are st

i suggest that you not tamper with the camera and try to find a qualified repairman for cameras and ask before that he examines it and tells you how much it will cost you. I have two nixes one of them has a problem wtih the shutter and I rather not touch
