Stiff focus ring In Leica Summilux 1:1.4/50 Leitz Wetzlar Germany

Stiff focus ring In Leica Summilux 1:1.4/50, It's not that hard to fix the stiff focus ring in this lens. Just take good care and REMEMBER to set small marks, BEFORE fully unscrew the helicoid!

I use LM47 with MoS2 grease from "LIQUI MOLY" to re-grease the focus assembly.
