Difficulty Turning Kinoptik Orientable Viewfinder

[Willem Jansen]

Hi all,

I’ve searched all around this forum and through Google but couldn’t find anything specific on how to actually turn the vf. 

Bernie installed it a couple of years ago and told me to: “force it a little, but it will turn every way. It’s designed to be tight so it doesn’t move around during shooting.”

But whenever I get it to turn,  with a huge amount of force I might add, the vf mount seems to come a tad loose and I can move the vf ever so slightly when it’s supposed to be tight.

I assume the little screw beneath the vf can be unscrewed a little and helps it turn better. But I don’t know if that’s actually how it’s supposed to be done. 

Anyone who can help me out?

(Attached a picture of the vf with markings to visually explain what I mean. Green = the little screw and Red = the vf mount that loosens.
