DIY Gearless Follow Focus
Firstly, this is NOT a Replacement for the real geared follow focus. But so far it works on my old 50mm nikon, 105mm nikon, 20-40mm sigma and the 80-200mm nikon.
This is a close up of the rail block showing the elongated cut on the bottom
allowing the clamp holding the wheel to slide and adjust to different
lens barrel sizes.
Bracket angle.
A later modification I made, changing the wheel size for better focusing accuracy.
Making a traction strip for those old and slippery focus rings.
Here is a short video showing this device in action.
Since Oct. 6, 2009 when I first posted this online, everal people have made their own versions of this and you can see some of their work posted at a forum thread at DVXUser.com.
I hope you find this helpful.
