Lens
Introduction
The goal is to setup a lens control in parallel of the camera control.
Use case:
- when the camera cannot control the lens
- the lens is not compatible (FX9 + cabrio lens) with the camera
When changing:
- iris/zoom/focus, we will send it to the lens
- shading, we will send it to the camera and it is transparent for the vision engineer on the RCP.
Timeless Quality
Our services are built to last, ensuring that every solution we provide is of the highest quality, bringing lasting value to your investment and ultimate customer satisfaction.
Lens compatibility
Specialty : B4 ENG
For specialty and robotic application, you can have a look at this guide
Cine/Photo lens
If you have a motorised cinema lens, you can follow this guide
Compatible with:
- Canon : using 12P port (digital)
- Fujinon : using 20P or 12P (digital)
- CMotion : using 12P port (ditial)
If you have a Canon photo lens (18-80 mm), it is motorised, but has only the 20P analog port that only allows control of zoom/focus. If you want remote iris control, you need to use external motor (CMotion, Tilta, ARRI, etc.)
NOTE
On this picture, you see a Canon 17-120 mm, that is normally controllable using 12P digital connector. But this port was already used by the ARRI AGITO operator (for zoom/focus). So here, they used a tilta motor to get iris control from the RCP in the CCU room.
Cables
- Lens controlled by camera : nothing to do, we control the lens using the camera protocol
- 2/3" B4 : CY-CBL-6P-B4-01
- Canon Cine Servo (12P digital): CY-CBL-6P-B4-01
- Fujinon Cabrio (20P digital) : CY-CBLL-6P-FUJI-02 + CY-CBL-6P-B4-01
- Other (non motorised, prime lens, etc.) : Tilta motors with CY-CBL-TILTA-SERIAL
NOTE
As lenses are critical, we recommend to use RIO-live instead of CI0.
CI0 is a slave device and if you remove the ethernet cable, the lens is not controlled anymore and will then "close" (iris).
While a RIO-live has all the protocols builtin and can control the lens on its own without any ethernet/RCP. It also allows to plug handles, USB accessories, etc.
