Repairing 50mm F1.4

this lens is a little bit too sensitive – after a certain time the inner barral will have an increased backlash – which will cause a less accurate focusing.

the solution: You have to change the cam followers.

Here are the prices:

So, 10 USD for each piece. thera are 3+2. Plus post. Spareparts: 50 USD….. not too cheap.

If there would be all 3 resp 2 in the price – then would be OK.


But ithout this, You will have always focusing problems.

I will try to make this parts from PTFE
