Hi Guys,
I'm new here. I'm a Brazilian focus puller. I'm living in São Paulo. 
I'm in negociations to buy a Cpro system. Witch cables do you thing that will be necessarie? I asked for Red cabe but in the cmotion website have more than one ARRI cables. Do you know what is better for control Alexa mini?
And what about pre marked-rings? 
Thank you.

Hi Clovis,
Here is a list of cables that I have ordered when buying cPro.
1 x *CAM to CAM extension
1 x *CAM to LBUS cable
1 x *CAM to RS
1 x *Cable CAM to Red (D-tap)
1 x CAM to EXT6
1 x D-Tap to LBUS power cable(this comes with the kit, but its nice to have a spare) 
You can also use Red cable for power if both dtaps break, so triple safe!

Thank you Klim.


And what you think about the pre-marked rings?

Well, pre-marked rings will always have the same distance measure at the same angle on focus knob. I almost never use plain rings anymore, although its good to have them. I got 5 pre-marked rings.

Hi Clovis, 
Im using the cpro now for 8 months and the cables and rings i would suggest:
pre-marked 0.25, 0.5 and 1 for long lens shots.
pre-markes iris 1.4


and cables:
CAM to EXT for Arri Mini (for cam. controle)
CAM to RS for older Arri Cams, obviously no cam controle
CAM to CAM, is to extend all CAM Cables when using longer zoom lenses
CAM to DTAP, when the ext port on a mini is allready in use with a monitor you can wire the motor with dtap and lbus. No cam. controle. Or, when working with smaller cameras like a Black Magic.
CAM to SONY (f5, f55 and Venice), for cam controle there will be released a new cable. Keep eyes on the website this week!! 

And obviously you 'll need some lenghts of LBUS to LBUS if you are using LCUBE-1 for the UDM or Cinetape readout.

Hi!
There is a lot of good information here already about the cables.
The one that you asked for, that’s made for the Alexa Mini, is the Cable CAM - EXT (6p). It supports Alexa Mini camera metadata, Start/Stop and there will be the camera control functionality soon.
About the premarked rings: I have my cPro unit for about a year now, and I use the premarked rings all the time. I have all 5 of them but mostly use the 0.5m and the 0.35m. I think that using the premarked rings is a huge help because your fingers „know“ the scale on them after a while, so if you use the same rings all the time every day, after a while you don’t have to always look at the knob anymore... ;)
