I bought a Tokina 24mm lens of the auctions site. With it came another Praktica and a Pentacon 50/1.8.
Not really needing another 50mm lens I'm not too worried, but the aperture is slow returning to wide open. Are these easily fixable or is this lens too cheap to be worth the trouble?

Need to clean , very common with East German lenses. Use it till it will be stuck wide open and clean it after. Sometimes works for years , sometimes just for days.

Yes, Attila. It's in this way.
I cleaned my flekt 35/2,4 blades, and worked for 20 days.
When clean again, I have a mistake and dissambled the blades.
Now I have to arm all the lens from zero.

Here, Argentina, the repairmen don't like this job. They say "a lot of work and few bucks".
More that repairmen, they seem financial men.

I always pay what they ask I pay their time same than fixing a modern lens , so they have no problem at all. Here cleaning cost around 30-35 USD. This is one hour fee for low cost businesses.

The problem is cultural here. The culture of the work was cleared us, then almost nobody wants to win with his work; they are in the hope of the golden business fills them of money without effort.
They filled the head to us with trivialities and now it is necessary to remove to thousands from people of that stupid dream.

http://gabriel.mp3-tech.org/blog/index.php?entry=entry080827-180800
This is the guide I used the first time I tried it.
Just so you know, I had the same problem, and cleaned the blades, but it came right back after only a few days. |

If anyone want the lens afterwards contact me...
