Hello,
This is what happen when you are in the middle of setting up a shot and you get distracted by others.
I overtightened the rear standard bearer of my f2.
There seems to be a small spring in the bearer that allow the large screw at the bottom to tighten the part around the rail.
This spring broke and now the knob is just loose i.e. you can trun it all you want it will not work.
Does anybody has any idea where I could find a replacement spring or if not a replacement bearer.
It gal me to have to purchase a whole rear standard bearer...

Cheers,

Luc
