Zoom Puller

[Jim Simon]

A lot of companies make focus pullers for lenses. Has anyone ever seen anything comparable for the zoom function of a lens?

Essentially I'm looking for a way to add "servo zoom" functionality to a manual zoom lens.

Should be able to use any follow focus or focus arm to achieve the same goal. At worst, you might need a longer arm for a stiffer zoom ring to make it move smoothly.

An as-yet unproven system. Initial reports are that some units make strange loud grinding noises.

It may look nice in pictures on the internet, but making a new wireless follow focus system is not easy. Ask C-Motion, they still haven't gotten it right. For me, it's Preston or nothing.
