Controlled zoom on canon stills lens

Hi all,

Is there a way I can do a smooth controlled zoom on a Canon photography lens?
The problem I have with doing it with my hands is it isn't smooth


I use a follow focus attached to the Canon lens. I attach a follow focus gear to the zoom ring of my Canon Lens and use a Follow Focus to zoom. It works quite well. I shoot a dance performance with my Canon 70-200 f/2.8 lens and zoom.
I have also used a Cinematics USB zoom controller with my Canon 5DMkII. It attaches using the camera's USB port and controls the lens zoom. It is a little jerky with the faster speeds, but at a very slow move it works good. It works best with the presets. But, I like the manual follow focus method the best. I have better control and better zooms.
I found that helicoptersean on e-bay sells great low profile hard plastic custom fitted lens gears for Canon lenses. They fit over the rubber ring on the lens and look more like a film lens than a ring that needs to be attached with a screw on rod.
Good Luck, and I hope this helps.

I have the Fotga DP500 follow focus. I got it from eBay.

I also like the Seamless Follow Focus Gears from

I like these the best. The Fotga follow focus works very smooth with little or no play. The follow focus gears are nice an can be left on your lens all the time.

I hope this helps.

You're going to want to get a follow focus of some kind.

Something like this would do the trick.

That's not the best one to buy out there but I just sent as an example.
