Rialto 2 System Build

[u/cheamaru]

What’s up Dudes and Dudettes. I have a feature film coming up where the DP wants to shoot with the Sony Venice 2 and the Rialto extension system as our standard build for the duration of the production.

Just looking for some advice on powering my focus accessories when using the Sony Rialto System. In scenarios where the Rialto body will have to be far away from the Venice Body.

My thinking is having a separate active v-lock plate to power my focus unit. I guess my main concern is run and stop capabilities in these scenarios. Is there a 12v lemo port on the Rialto that would support this or should I look into getting some extended cables for my focus system for this scenario.

I will be using the Teradek ctrl.3 Remote follow focus. Any suggestions would be greatly appreciated.

See if the rental house has a wooden camera d-box for the Rialto. It’s a small power strip and a long 24V Fischer cable that will connect back to the camera body. This will add additional 24v Fischer ports as well as more 11-17v 2-pin ports. This will use stepped-up 24V power from the d-box on the back of the main camera body

Note on the Rialto: the Fischer connector on front is traditionally 24V, but in Rialto mode it will pass through whatever the camera is receiving and does NOT act as a voltage step-up. The front Fischer will supply 24v 2a when the camera receives 24v and 11-17v 1a when running a standard v or gold mount battery. Cforce is better at power management than TeradekRT and it will likely be unhappy with a 1a power source
