Hello,
I would like to start and clean this lens:
So far I have a wrench spanner and the usual set for cleaning the lens from the outside, microfibre cloth, the spray, blower and the dust removal.
What else do I need:
Slotted screwdrivers? Size? 0.8 mm, 0.9 mm
That rubber things to take the front spiral?
eBay? anyone from Moscow? )
Thanks
Domiplan 2.8/50 opening
Re: Domiplan 2.8/50 opening
I think that you can use a wide rubber plug to remove the front part of the lens. What works well are the rubber caps for a crutch or a cane. You might be able to find them at a drugstore.
Be careful when disassembling the lens and aperture ring, as there should be small ball bearings that make the aperture "click."
I probably would try to go in from the front. Remove the front face of the ring, and the rest of it should unscrew easily.

Not familiar with the lens. From your picture it seems that the dirt / damage is in the front element, so I would start from the front as MIke said. Good luck.
There are several videos in Youtube about disassembling the Domiplan but in M42 version; probably the aperture mechanics are somewhat different for the Exakta version.
Mr. Subbarayan_Prasanna in photo.net has many posts on cleaning / repairing Exakta lenses and cameras, you may check with him.

Re: Domiplan 2.8/50 opening
thanks for the tips Julio and Mike.
I tried as the videos about the M42 but the outer ring its not just 'pop' with an screwdriver, I will look for the rubber thing and take a look in photo.net.

That looks clean! Now, to test it!
And then you will find the Exa limitations and need an Exakta body....

I already found it when focusing with it, I see the object to focus at around 6-7 meters and the focusing ring says its 1.5 meters.
Or maybe I put one lens wrong XD

Re: Domiplan 2.8/50 opening
Did you collimate the lens? I'm going to redo my instructions, but you should reset/confirm infinity focus after you work on a lens.
Maybe you also put one of the elements in backward. I've done that before.

Re: Domiplan 2.8/50 opening
No need to collimate it I think, I just took out the front two lenses, the moving one at focusing is the read one, which I didn't take out. Also I checked on the net how the domiplan lens design is and I did it right...
I will take a look again...
