Need help - Zeiss Ikonta 521/2

[Janos]

Hey there,

a couple of weeks ago I purchased an old Zeiss Ikonta 521/2 with a Novar-Anastigmat 11cm/4.5. The rewind knob was missing so I got it fairly cheap.
Yesterday I got how to dissable the (with the rewind knob missing now permanent locking) double exposure lock. Sadly at this point the shutter broke with no obvious reason.
Before it was already sticky and not properly working at the times 1/25sec and B, so I released the shutter a dozen times or so. This worked just fine, but suddenly nothing happened anymore. :bang:

So I tried to disessamble the lens, but after the front lens I cant see how to continue. Is anyone here familiar with these old cameras?
I really need some help. The Ikonta is simply too beautiful for letting it die like that. 🙁

Janos, on a medium format roll film camera, there is only a winding knob. The film doesn't need to be rewound after it has been exposed.

Before you get too far into the repair, doesn't this camera use the no longer available 116 film size?

With regards to removing the middle element of the lens, you may have to first remove the front fascia ring that says Zeiss Ikon or whatever is written on it.

Good luck,

Alright, so the winding knob was/is missing. 😉

This camera takes 120er film. So that wont be a problem.

The front fascia ring has already been removed, the next stage not as seen on the photos. 🙁

Zeiss Ikon cameras that end in "/2" are 6x9 on 120 film.

To remove the middle element, you often need either a rubber plug (press and turn) or a strap. Whatever you do, don't use pliers. The barrel is brass and bends easily.

I have a rubber plug here and tried that already without succes.

For a strap there isnt enough space because of the ring right next to it.

If thats the one solinar meant (sorry, I thought you meant the ring around the front lens), then it would be interessting how to remove it. I found no way.

I see your photos and see what you mean about a strap not fitting. You need a very thin strap.

One thing you might try is to put a small amount of lighter fluid into the outer threads of the middle element (the one that's stuck). Then use the rubber plug to tighten (yes, tighten) and then loosen the element. Sometimes, tightening it will break free the frozen threads.

Also, try a quick, hard untightening movement.

Otherwise, you will need to try to find a thinner rubber strap. I've had a few that took a lot of work to remove.

 

[Janos]

Thanks a lot! I will try that.

A rubber tool is mostly used for this kind of work but sometimes there are lens elements which even then don't want to come out.

A trick which helped me several times is heating things up with a hairdryer (NOT a paintremover) for some minutes. This also softens gummed up grease and widens the ringdiameters and thus giving less friction.

Use a rubber sheet or a soft rubber plug, get a good grip on it and just turn it out.
