We know how time is of the essence on the set, and even a few seconds can seem like an eternity. My AC is always present on the set nearby me for 95% of the time, but the few times he is not can be crunch time. When I have to frame a new shot and need to control the focus to show my idea to the director, the OCU is a god-sent. One push of the button and I can focus myself. And afterwards I don't have to worry to switch anything back, the AC just grabs it back remotely.

The OCU-1 is a small and compact unit and felt like a part of the camera setup right from the beginning.

I am actually now on my fourth show using the OCU-1 as my digital follow focus. I use it almost everyday to be able to do rehearsals at camera with my operator and then send control back to my WCU-4 hand unit if I can’t stay at the camera.

The OCU-1 is a good supplement for lens control on a gimbal.

It makes my work fast and much easier. This is exactly the tool we have been waiting for a long time. From now on it is a fixed part of my camera equipment list.

The OCU-1 was great. We had it on the camera most of the show and it was really useful, Greig Fraser ASC really liked having it on there.

It’s nice when setting up and you left your handset on the magliner.

OCU-1 FAQ
-
Can I use the OCU-1’s override feature with the SXU-1?
No, currently only the WUC-4 supports the override function.
-
Can I use the OCU-1 as a standalone unit without the WCU-4 for controlling focus, iris, and zoom?
Yes, the OCU-1 works the same as the Master Grips.
-
Can I use the OCU-1 as a separate tool for iris control while using the WCU-4 to control focus and zoom at the same time?
Yes, the OCU-1 can split lens axis control with the WCU-4.
-
Does the OCU-1 work with a servo lens?
Yes, you need the LCUBE CUB-2 for it. With AMIRA it works like any other ENG lens.
-
Does the override function work when the WCU-4 is hardwire connected with ALEXA Mini using the cable LCS to EXT (K2.0007624)?
No, currently this override feature is only possible with the ALEXA Mini LF.
-
Can I add camera user buttons to the OCU-1?
Yes, it is possible to assign camera user buttons to the OCU-1 and control up to 3 camera user buttons per OCU-1. The corresponding function of a user button can be set on the camera. Please check the designated camera user manual on how to set the user buttons.
-
Can I adjust the speed of the wheel?
Yes, you can assign SPD+ (increase speed) and SPD- (decrease speed) to any of the OCU-1 user buttons and also set the motor speed from minimum to maximum within the motor screen. The speed is set as the ratio between lens range and wheel range (1:4, 1:2, 1:1, 2:1, 4:1).
-
Can I use the OCU-1 override feature with hand units other than the WCU-4?
No, the override function is only supported by the WCU-4.
-
Does the motor jumps when giving back the lens control from the OCU-1 to the WCU-4 or taking back the lens control with the WCU-4?
No, the WCU-4 indicates the override mode which is triggered by the OCU-1 and offers a re-engaged lens motor control method without a jump.
-
Can I set motor limits on the OCU-1 while I am in the override mode?
No. This function is not supported in the override mode only when the OCU-1 is used as a simple control unit which controls selected lens axis separately from the WCU-4.
-
Can I use the OCU-1 on 3rd Party cameras too?
Yes, you can use it on other cameras than ALEXA and AMIRA but with limited functions. For further details about extended compatibilities please check the designated OCU-1 user manual.
