Arri lightweight follow focus with RED lenses

[Ronnie Wenngren]

We are going to buy a used Red with MX upgrade and I have a few important questions. If you can't answer them maybe you know someone who can.
We had a Arri Super 16 SR and have kept some equipment for the red. radio focus, mattebox etc.

We have a Arri lightweight follow focus - the older version. Are we able to use it on lightweight support together with the RED 17-50mm T2.9 ZOOM and the RED pro prime 85mm? Do the lens diameter allow us to use that follow focus?

We are also looking for a used Zeiss 85mm 2.1 - as an alternative to the RED Pro prime. I read the color match are good between the RED zoom and the primes but are the color match working between a RED 17-50mm and the Zeiss 85mm 2.1?

I hope someone know this.
Thanks,
/Ronnie, Sweden

I don't know about the RED 17-50, but it does not work with the RED Primes. They are just simply too big. Ziess should work just fine since it's got a much smaller barrel.

Ah, thanks. Too bad - we are planning to go lightweight with everything. I suppose the 17-50 are as big as the primes because of the front diameter. :/
Thanks for important information - we must talk about this now.
