How can I make the focusing slider moving well?
« on: February 07, 2018, 03:53:45 AM »
Hello, I'm having problems with the focusing slider.
As I move the focusing slider, the focusing slider becomes more stiff and harder to move.
As a result, it is difficult to adjust the focus.
How can I fix this?

Thank you.
