Remote IRIS control for 3rd party camera's

One of the main prerequisites for any professional multicamera production is to be able to control the exposure of each camera; to make them match each other.
In older camera's it was also necessary to control the pedestal and colours as an on going function.

But now with more modern camera's the pedestal and colours really only need to be set up prior to the event as they have far better flare compensation and very stable colour control.
Of course there are minor issues with gamma settings between different types of camera's, but no where near the nightmare of a few years back where you would NEVER use different types of camera's on the same shoot.

To use a camera with remote camera control units (CCU) can be very expensive. I use to run an OB company where we had 16 triax camera's, each costing in excess of $60,000 EXCLUDING the lenses!

But now I do more or less the same thing but with FAR cheaper camera's, albeit while missing many features of the more expensive camera's.

So I use ATEM switchers including Studio converters with a few Blackmagic Studio Camera's (and of course my GVG control panels). But I also want to add to the mix some 3rd party camera's; in my case some Sony EX 1's and some older HDV camera's such as the Sony Z1 and Sony FX 1's that connect using the camera converters.
The BMSC's are great because they give me full CCU control. The other 3rd party camera's can be initially balanced to look very much the same as the BMSC, except there is always the need to call up the camera operator and get them to adjust the iris; bummer.

I have now developed a remote iris control for my 3rd party camera's that can be controlled by the ATEM CCU control panel (also available on my GVG hardware panel). On the 3rd party camera's I attach a servo motor to the iris ring.
I connect these using a network cable but am in the process on controlling them over a wireless network; NO CABLES!
These controllers also provide prog/prev tally lights for when using without the camera converters.
They are also great for my wireless camera's using HDMI transmitters. Also, they can be used with the BMSC when you have a B4 lens fitted because there is currently no interface for them between the lens and the camera body.

I will be selling these IRIS CONTROLLERS shortly and will also be looking at adapting them for many other brand of 3rd party camera's which will include interfacing to the LANC where many have the Iris control and will avoid having to attach the Iris servo.

I am also in the process of making dedicated CCU remote panels for the ATEM; one for each camera, that controls all the features as the ATEM software control panel does. Obviously only the Iris can be controlled on the 3rd party camera's ATM.

If anyone is interested in the above feel free to contact me and I will see what I can do.

Also, if anyone needs a GVG control panel to control their ATEM, contact me; I currently have one on eBay

and have a few more making their way through the system.

Very interested in this, but

Very interested in this, but have some function requests... 

Please make it work without the ATEM. Increasingly I use other switchers on jobs and do not want to be tied to a product which has proven to be unreliable. 

Please make electronic interface connection to Sony XDCam cameras such as the PMW200 / PXW200 these have WIFI control already so it's just protocol translation. Or via the lens remote socket, but we need local zoom dmeand pass through in that case.  or whatever, i don't want a thing which bolts on and needs power. 

Please try to keep costs reasonable! If you can come in at less than $1000 per camera then i will likely order several units. 

Please consider "touch down" router control to switch the engineering monitor from the CCU controller.

good luck

cheers

There is a CCU controller

There is a CCU controller from datavideo, that can control up to 4 Sony cameras by the internal rs422 from Sony. It costs about $1000 I think.

See video

You can use the ATEM CCU interface (including 3rd party controllers) to control a NON BMD camera, OR use it to control the IRIS of a a B4 lens attached to a Black Magic Studio Camera.

This video shows the IRIS being controlled remotely by the CCU control of an ATEM switcher as well as my own Grass Valley control panel interface.
I have been using them for some time now and decided to make them available for sale to anyone who is interested.

This development will expand out to all available camera's and will shortly be controlled over a wireless network.

All components are made on my 3D printer so there is no big deal about small quantities.

I would like to buy 5

I would like to buy 5 of these for our church. We are currently using cameras without iris control on our ATEM 2 ME and would love to add this capability. Please let me know if we can still get these and how. Thanks.

What camera's are you using?

What camera's are you using? Obviously the 'servo mounts' are different for each camera.

Also, if you are controlling 5 camera's you may need my 'ATEM Server' that allows 7 ATEM

connections using only 1 ATEM interface socket.

Baz - ATEM SERVER / Iris Control for Canon EOS?

Hi bazinoz,
is there a demo or demo video of your ATEM SERVER?
i have a canon eos 500d and wanted to control the iris, focus, etc. via lanc protocol

or arduino mega. Do you have a solution or idea to do that?
thank you

Philipp

CCU

Hi Baz,

I'd like to get some of these CCU controls. The issue is that I may use for Sonys, Panasonic AF102 or for GH4. What can you suggest?

LANC control of IRIS/ZOOM and Tally via RS485 & POE

Hi,

 

I realise that i need to start documenting my 4 year running project.

I have made a system that uses a combo-cable that combines COAX and UTP.

The COAX is used for the HD-SDI from the camera, the UTP is used for a number of things:

- POE to supply the camera

- RS485 for remote control

- Intercom

 

There is a operator box (beltpack) connected with ethercon to the cable, where an isolated POE splitter is making 12V out of the 48V POE. It also houses the RTS-TELEX clone circuitry for the intercom.

From the beltpack there is a cable which carries some signals to the camera.From an old Sony FP970 battery i made a housing to get from the 12V to the 8.4V camera supply  (SMPS DCDC), as well as the RS485 receiver for the remote control. This is based on a PIC controller that acts a a LANC inserter, where it is able to give LANC messages to the camera for IRIS/ZOOM, as well as accepting an external LANC zoom controller for the operator.

The PIC also drives TALLY lights that are controlled via RS485 commands.

The RS485 transmitter is based on an arduino, that receives the tally info from the ATEM, and uses another ethernet port for getting the IRIS commands.

First prototypes are now operational, but making full-fledged decent software and a design for a remote control panel are still to be done.

Anyone interested in such system and willing/capable of speeding up development work?

 

Kind regards,

 

Bertrand
