I just have NN5L now since a few weeks and I wonder what I do wrong as when I tighten the upper arm it will not stay that what. It slowly moves down and it is really hard to tighten the knob so just that the arm stays a 0 degree.
How can I convince NN5L to stay that way. Is there a trick somehow? BTW I use a Canon 40D with a Tokina Fisheye. So normally also not to heavey for NN5L?
I appreciate all kind of supprot.
