Focus Controllers?

Hey all,


I rarely even wander in here, but a friend asked me to help him with a small video project(all stationary and pre focused stuff)...


BUT....

has anyone see these before? or used them?

my thinking was: Surely someone must have found a way to control a lenses's autofocus motor externally?

And usually if I'm thinking of something, SOMONE else has the same thought as well...

They have, and there are a few different routes. This is one I have been waiting for personally: LINK

Ive seen a few reviews on the Okii but also have seen quite a few people but them and then sell them, so I dont know how well it actually works.

You can rack focus with Magic Lantern but it is too noisy to be a viable option.

I can see the point for remote control but, for hands on stuff, the simplicity and reliability of a conventional follow focus takes a lot of beating.
