Birger mount and focus

[Emanuel A.]

Will it bring any advantage over the other options beyond the use of DSLR glass as common manual SLR lenses?

Feedback from the lens to the camera in a similar manner as Cooke's /i technology, as Eric put it, it's a Babel Fish for the various lenses that can be stuck on it converting the data to a certain format.

Control over focus using a traditional focus wheel with no gearing issues. You don't need to setup the follow focus each time you put a new lens on setting up the gears against those on the lens.

Control over aperture on lenses that don't allow manual aperture alteration.

Remote control focus/zoom/aperture capabilities (I believe) saving the weight of three motorized follow focus systems and lengthy setup on your rig.

Can't think of anything else for the moment but I'm sure I'm missing something!

Thank you Paul.

But I couldn't understand if I've been following properly...is the focus control executed from a PDA?!... For instance?

No, what I meant by traditional focus wheel is the attachment focus knob that you can purchase for the birger mount. It attaches via a wire to the mount and when you turn it back or forth it acts exactly the same as a traditional follow focus will by using the automatic controls and motor built into the lens. Unlike a traditional focus wheel you do not need to align the gearing on the lens to the gearing on the follow focus so changing lenses should be even quicker.

You can however forego the focus wheel and simply use the remote control or a PDA or at a later date use Curt's remote control in order to operate the focus, aperture and zoom remotely.
