FS7: Speedbooster suddenly iris/aperture jumps

[sly]

Hello,
I own my fs7 with speedbooster ultra since it was released.
but last week the iris control does not work correctly with my speedbooster any more
tried different lenses- same same

I adjust the iris and while shooting, the aperture jumps to wide open
andthen suddenly I can turn the iris and the aperture doesnot change

Any ideas
I do have the newest firmware on bothe fs7 and speedbooster
is it broken?

thanx for any advice
Sly

Try making sure all the contacts on the speedbooster side are clean and not stuck in a recessed position.
