Eng Lens for F3

[Mwjace]

I Just watch a albe Cine Blog on a ENG set up for arri Alexa camera http://blog.abelcine.com/2011/07/21/abelcine’s-alexa-one-man-band-kit/ While i don't have a need for the audio stuff, this b4 to PL adaptor intrigues quite abit. http://www.abelcine.com/store/HDx35-B4/PL-Optical-Adapter/ I am Wonding if there is a way to power a servo zoom lens with the F3. I'm not sure i want to but I'm curious can we, is there something out there?

Might be kinda cool
