Can you guys remind me what plugs the Red has for ENG lenses? I'm about to buy a Fujinon 13x4.5 BERM and want to make sure I get the right ones. Thanks!

I have the Fujinon 13x4.5 and 22x7.3 HD zooms, and a prototype RED B4 adaptor. I've shot quite a bit with them on RED #8 in the past few months - with good results. I've been shooting in full manual, non-power mode.

The RS232 bus on the right side of RED can power B4 2/3" lenses. A custom cable, not made yet by anyone, is needed in order to get full lens power and functionality.

I have communicated with Fujinon and they have supplied me with the advice and pinout for their end of the lens cable. A hirose connector is necessary to adapt the Fujinon multi-pin cable to RED. On the RED end of the cable, special LEMO connectors are necessary. Care must be used in making sure the cable maker follows the pinout diagrams for RED and Fujinon in making the cable.

I have two of these cables currently being made. When they're finished, I'll test them out with the 13x4.5 and 22x7.3 zooms. I will then be able to start/stop, record, and power zoom all on the servo zoom hand grip on the side of the lens - thus enabling true EFP functionality.
 
Gibby,

Thanks so much for the thorough feedback. So when I'm ordering this lens, should I not order any cables (for power) as they will not work on the Red? It would be nice to have servo zoom, but it sounds like this might not be possible without a custom made connector. Thanks as always!

I ll be more than happy to know who can make this cable/adaptor,
would you share this precious information ?
 
Would you know where I could find somebody to make a cable /adapter to fit my 6x8 Canon ?
Thank you

I take it from this quote that I would not simply be able to plug in the 12-pin cable from the Fujinon into the 10-pin on the Red in order to get Servo Power? Is there any way to get Servo Power without this custom cable (which I'm anxious to buy once it becomes available!). Thanks,

Peter

That's correct. We use a LEMO connector for enhanced reliability, and to match the other uses of this port that already used LEMO. So you will need a LEMO to Hirose adaptor. We are building up sample quantities for field tests (lab tests have been successful)

Peter, I hope these photos help you understand the cable that you need. PM Pana-Tech and he should be able to advise a cost on the cable required.

In theory you should be able to control your lens servo and hit record from the lens VTR start button using the adapter cable.
 
Thanks Rocketeer! Very helpful info. I will PM Pana-tech and report back. Best,

Peter
 
Hey Gibby,

When you have a moment do you think you could post the pin out info you received from Fujinon for the custom cable? This would be a huge help to those of us looking to get one made. Thank you!

Peter
 
This is great news Stuart! Can you tell us what functionality will be available through the lens? Zoom, record, anything else? Thanks!

Record Start / Stop (lens VTR button)

Last Clip Playback (lens RET button)

12V D.C power for the lens zoom motor

The Iris and focus will be manual.
 
In case you know what you are doing:

So basically:

Pin 1: Ret button.
Pin 2: Record button
Pin 3: Ground
Pin 6: +12v
 
I have made and tested a cable. Rocketeer's words were "Holy Shit, that's great" Not sure how many would require one.
 
So I should be able to this port to make a remote roll switch?

Yes, but you may find it more convinient to use GPI/O 4-pin lemo connector instead.
