An August weekend


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.

Next level gagdet. Gain additional on-board control using remote-focus systems.

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.
