edelkrone Focus Module for Select Stabilizers and Sliders

This piece of gear is part of the exceptionally smart Head Plus system..and it is very smart too. It does what it is supposed to do, and it seems to do it well.Cons: 1) The motor housing is large and takes up valuable space near the focus gear. I have two lenses that won't work because the focus is too close to the lens hood... the hear can't make contact with the lens unless I remove the hood.2) Why Edelkrone... oh WHY don't you include a power switch? As soon as you plug the wire into the Head Plus, the focus module starts trying to calibrate the lens, even if no lens is in contact. 3) I think this unit is shockingly overpriced for what it does. and I would love to have it work separately from the Head Plus... but alas, this is not usable in any way except when plugged in to other Edelkrone gear.All told though... this is needed for the Head Plus and Slider... so I will put up with the shortcomings.
