I have a pentacon 50/1,8 from 1987.

I never sold the because nobody wanted it. Well, will be mine for ever.

It has a movement to tilt at the focus mechanism. You have firmly the rear of the lens with one hand, and with the other you move the front of the lens, it wil move (not the rear) in the tilt form.

The focus mechanism seems to be worn away or so.

How can I repair this?

Rino.

I cannot because it is disarmed. Sorry

Thanks. Rino

Luckily I managed to solve the problem How?
I disarmed the lens. In the helical spiral of the approach I placed liquid silicone soon and screw.
Later I returned it to unscrew, I let dry the resin and soon I removed the leftover.
I lubricated and voila! Now I turn the approach spiral and no longer moves towards the flanks.

To whom it may concern.

No a tilt lens, nor moved as it.

I said it very bad. Embarassed

When you focused the lens, it moved 1 or 2 mm. because the screw were bad, it's an old one. It didn't a tilt lens. Very Happy

Thank to you.
