Focus ring for VX-2100
 
I am looking for a focus ring - an extra ring that attaches on the lens and helps you change the focus betwwen two dif spots - I don't know if it sounds confusing, can't explain in it any better.
If any body has an idea of where can I find something like this, I would appreciate the help.

The VX2100's focus control is motorized, and the focus ring on the camera controls the focus motor, and does not adjust the lens directly like on a manual-focus camera.

Troy's right, and if you turn the focus and zoom ring slow enough, nothing happens - you don't generate enough electricity to feed the circuits. So the idea of having an attached lever with end stops wouldn't work - and you can test this out simply by using a chinagraph pencil on the focus ring and doing some focus pull experiments at different speeds.

Yes.. I didn't thought about that. You are right guys, thanks.
Well, it was just an idea:)

Thanks again
Anthony
