Comparing solutions... [related to Birger's mount]

[Emanuel A.]

What's the difference between a traditional follow focus and a Birger's one?

Does it take advantage from the lens' AF motor?

Any guess on the performance?

That's the idea.



Any guess on the performance?
According to Erik, pretty smooth. Hopefully we can get a prototype for the LART and know for sure.

Can the AC or Focus Puller pre-program the focus marks? Will the follow focus be automatic from there then?
