Mamiya RZ lens(es) on Epic, compatible with a follow focus

[Jared Roessler]

Well it works. Takes about $400 worth of stuff and a handful of hours to build, but it works.





Footage to come. And these lenses breathe quite a bit, as you would guess.

Had it over at ARRI/CSC in New Jersey on Wednesday for a camera checkout, there were fitment issues when we tried it on an ARRICAM ST but it works fine for Epic or One.
Just thought I would share and answer any questions if anyone had any.

so, what are the bits? macro bellows to what to PL?
which focal lengths of Mamiya lens did you use?
and is this to prepare for Dragon?

[Jared Roessler]

Macro bellows, adjustable plate for macro work, better bearings, a riser block and an older style RED rod bridge. It's set up here for the Canon mount, afterwards I affixed a PL mount to the canon bayonet for the test at ARRI.
I tested it with a 50mm, 65mm, 75mm, 75mm shift, 90mm, 90mm RB-series, 110mm, 127mm, 140mm, 180mm, 250mm, and a 100-200mm zoom. The zoom is a little weird but it would work with a FIZ.

I guess it'll be good for Dragon but that's not why I made it. It's mostly a proof-of-concept for a prototype. Also, I had recently built a much simpler rig for stills on my DSLR and figured what the hell, couldn't be that much harder to build one for vi

Known issues:
Takes a speedcrank to use effectively.
Gearing is reversed.
Breathing is noticeable.
No witness marks whatsoever, no place to mark distances.

Like I said, this is mostly a proof-of-concept for a prototype. I'm sure it will see some use on some of the fashion and beauty stuff we shoot/rent support for, but for now I'm just pleased that it's possible to use these distinctive and unique lenses for video.

I seeing a shift/tilt rig a-comin'... Cool!
