Markup Focus wheels


Thomas Gleeson
 

I am looking for suggestions for the neatest way to markup my Follow Focus. I generally use my own personal set of primes and have bought a disc for each lens. Whatever the approach ideally it would be semi permanent or reversible as I do use other glass. I have terrible calligraphy skills and I was wondering if anyone was printing up the focus scale or some other clever approach?

It is possible to 3D-print FF-rings with the scales as indent and then filled with a contrasted color.... But this will have to be custom-made for every lens.
I've 3D-printed (plain) extra rings for the WRC-4 and Heden handsets....  It's not a quick job for sure.

Hi Tom,

Before I start coming up with ideas, what Follow Focus system do you have? Arri FF4? WCU4?

Steven,

I couldn’t resist the amazing price of the CINEfocus Pro Follow Focus As an owner operator my FF is only a backup or for small jobs and on bigger projects AC bring their own systems. So far it's proven to be a more than capable tool. 

I like the 3D printing idea although I suspect its a complex process as you would first need to scan the original disc then create a CAD file then accurately translate the focus marks onto the CAD drawing. No easy task.

Wow! Shoot35 is still around! That takes me back. I just discovered the other day the Letus is still selling 35mm adapters. Amazing what we used to put up with...

Anyway, most marking disks are quite simple shapes that wouldn't need to be 3D scanned in order to create 3D printed copies, just measured. Flat focus rings (FF4 style) could be laser engraved fairly quickly as well.

That said, I think simply 2D printing onto good ol' label paper is a solid solution. Wrap it in j-lar and it should last a while.

Best,

Tom, it is surprising how helpful certain software can be, even the free programs.
I would like to try one ring, to see what it can archive. I have to use that printer for useful things.....

What I need is the inner and outer diameter of the ring you want to copy, the thickness, where the locking pin goes and how far. 
Basically a picture of the ring, seen from the top (no perspective or distortion) and with the marking-stripes accurately placed. The numbers can be a bit wobbly, they will be replaced with a proper font. And the brand/focal lens of the lens.

This is a piece of cake using Solidworks to draw the part and generate an STL file to print it. Takes little time.
