Would you like a radio control focus system?

Hello guys please email me if you want to stay updated on a radio control follow focus system for use on the dvx100/A for shooting cine style on a steadycam/dolly. This will allow the focus puller to sit with the monitor on-set and do all the focusing lots easer then being with the camera...I am working on the design now.... I have one for myself that is homebrew that works great and now I am working on a professional version forsale..it will work PERFECT...my email is:

oolsen1@ec.rr.com

thanks!

Don't keep us in suspense any longer. How much do you think it will sell for? I'd love to be able to do follow-focus on this camera.

I never believed in the myth of DOF. If DOF were so great, why wouldn't all cameras be shipped with 3 focus positions, small, medium and large? Next to aperture control, focusing is the most critical control you have on a camera. It means the difference between an amateur result (my specialty) and a professional one. A camera in motion without focus control is like a near-sighted driver without glasses or contact lenses. Blurry.

More Info, Please

Obin,
Sounds interesting. Certainly there are already remote focus pulling systems but they are quite costly...more than the DVX100 camera.

On critical performance item for such a device is precise repeatability. How does the operator of your device interact with it?

yes you will hit marks with this unit...very important as you say :) i am thinking marks on the transmitter unit so that you know what marks you are hitting OR you can just watch the monitor and hit your"marks" via onscreen video feed... this will NOT be a free spinner type device :0

Marc:

The large DOF with DV cameras is not unsubstantiated. I think it safe to say that any DV camera at a wide-angle setting has a vast amount of depth of field, even at close to wide open it's not surprising to be able to hold 4 feet to infinity. It gets trickier as you zoom in. The long end of the zoom for many cameras (the DVX100 doesn't go as long as the standard XL1 lens) is actually extremely long in photographic terms, and the depth of field shortens considerably. This is when more precise focusing becomes an issue, no doubt.
