Ikon ZM suddenly malaligned

[Peter_S]

Hi!
So a couple of days ago the ISO/aperture dial wheel flew off. No big deal I thought, put it together again, ISO and aperture work...but oi, the rangefinder surely not. In 90cm the focus is off 30cm, over 5m it is off about 2m (shows 3m). 😕

I doubt somewhat the one relates to the other, but according to my memory I did not knock the camera against something and it worked fine before the dial wheel came off. Any ideas what could be the cause and potential cure (besides a journey to Oberkochen or the two seperate and sealed calibration screws)?

Cheers,
Peter

It seems to me that the link that you provided me with has the information that you need should you be brave enough to give it a go.


That sure is a puzzling event. That is rather a large sudden misalignment. If you look at the link that you provided, there are focus adjustment screws local to the shutter dial.

Most likely, one event was somehow related to the other.

Hi!
Thanks. Yeah, I was suspecting that screw...
Odd is also: the 25mm Biogon does not move the finder windows below ca 0.65m, so between 0.5m and 0.65m nothing happens in the finder...

Cheers, yes, you are right, that is normal, I forgot!
Self-calibration...I am reluctant for warranty reasons

If you are under warranty then get the camera off to Zeiss. I'm in the U.S. and we ship to a representative in NY and they ship to Germany. I think that it took about five weeks to get both cameras back into my hands. I sent them in for alignment problems...subtle alignment problems.

I kissed my Ikon and it went out of alignment. It happens from time to time but I just back hand her and she goes back into alignment.

Is it also out at infinity? Is the error the same amount, in terms of the rotation of the focus ring of the lens, at each distance? Have you tried it with another lens? I would answer those questions before starting to make any adjustments.

The most likely place for the error is the prism (circled green in my picture above). But read my instructions before fiddling or you might have the whole thing come off.

The screw circled red will, if anything, adjust the vertical alignment so I would leave that alone.
