Motorized zoom lenses

Brian_Siano — Sun, 08 Jan 2017 12:55:34 +0000

Does anyone know of any lenses, or kits, that run the zoom through a controllable motor? There's a project where I'd really like to have a long, slow, and smooth zoom. And while I could use a follow-focus rig to run the zoom ring, it'd be a bit jerky. Are there kits that enable motor control of a focus- or zoo ring, with highly variable speeds, so I could make my zoom last as long as I want?

FLEX Seamless Follow Focus Gears by Proactive Group

Seems precise made and inexpencive (US $9.90 on ebay) compare to other rings. http://proactivegr.com/gears/

The gears are designed for ANY LENS diameter from 50 to 93mm!

Separate gear made for each diameter of 1 mm increments!

The gears are made of rigid polyurethane, that stretches a little bit, when you put the gear on.

The correct form of the teeth module 0.8.

Choosing gears for follow focus

I recently purchased a new (Gini) follow focus and am looking for recommendations on good gears to go with it. Are zip gears worse than standard gears? Anyone used these:

http://www.ebay.com/itm/170648910462?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649 - they look like a good price.

Also I'd be interested in 360 gears, but haven't seen many on the market.

Silencer Follow Focus

Everyone check out this new follow focus system being developed for DSLR's. Its a follow focus that the cam operator is able to remote trigger while filming. I haven't seen anything like this. Looks great!

Nice DIY 360 degree lens gears on the cheap

Aside from being a bit tense thinking this guy will eventually cut himself with the knife, I think he has a good idea on how to make inexpensive, semi permanent, professional looking lens gears on the cheap. Just don't cut yourself making them :)

Old m43 gears

I rarely use GH2's touchscreen and ETC features. Hope Panasonic don't go higher than 16MP.

GH2 has shorter shutter lag and faster AF, but I like GH1 for static photo. 14MP magic? I'm gonna carry GH1 + 14mm 2.5 to capture this fall season.

GF1 is slower than GH1, but the static photo looks special. 12MP magic? I don't own it, but I like its rugged body. My GH13's body coating already began peeling off.

It's good to keep the good old GH1 or GF1 body. Especially GF1.
