Does anyone have an idea about how to run a follow focus on a camera with no teeth on the lens? for example hvx200 or Sony z1u.

There are external gears that can be bought for such things. A quick search turned this up:


But I'm quite sure there are others, not sure who all makes them. Never forget you have a friend in Google!

Add on gears are the way to go for almost all such cameras. The only except is some of Canons HDV cameras. They have an autofocus sensor which is unfortunately in the way of where the gear would go. There is a manual follow focus made specifically for these cameras that uses a large soft rubber wheel instead of gears that works relatively well. I managed to use one of these to attach my follow focus motor by having its gear push into the soft rubber wheel much in the same way it was pushing against the lens. Worked surprisingly well. Should be possible to attatch some sort of similar rubber directly the the motors gear to have the same effect but I don't think anyone has done it.

Redrock makes them too: http://shopping.nets.../it.A/id.185/.f

Works good for me when I get one of those small cams.

Size D fits the HVX.

I can't remember what camera but I've used velcro, hard side on the lens and soft on the motor, makes funny noises but it worked.

My Preston completely shredded a cheap plastic add-on lens gear during calibration on a job where we were using a Letus adapter and Nikkor lenses.

The fix was two of those big fat rubber bands they had in Crafty that come on the heads of broccoli, one around the lens barrel, one around the gear on on the Preston, then I used a Bongo-tie from the opposing side rod to keep the motor pulled tight against the lens. It wasn't pretty but it worked well enough to get us through so now I keep a couple of broco-bands in the kit.

The "Broco-Matic Elastic Motor to Lens Mount System" coming to a produce department near you...

I did actually try rubber around the motor gear but I didn't have one to fit over the lens barrel and it didn't work so well. Next time I will try it on both.

May not sound/look too sexy, but rubber bands were a staple in your kit in the days of the Seitz and horizontal Heden motors. Trying to get those motors to stick to the old Zeiss lenses (or the fine pitched video ENG lenses) was a chore. We have it SO good now (in terms of gear) its not funny!
