The lens hood on my Leica Q2 has seized at an oblique angle. The threads have been rough for some time. We’ve cleaned the threads with delicate brushes of various stiffness and lens cloths. No positive results were achieved. The hood is now firmly stuck.
Over the past months, we refrained from using any lubricant. Is there one that is Leica approved?
We need to get up and running pretty quickly. Do any of you have any suggestions?
