Quotes

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

Cinematographer Eugen Gritschneder (Known for: Racko - Ein Hund für alle Fälle, Tackling Life, Mollath, Familienfieber and many more)

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.

Gimbal System Operator Bernhard Russow (Known for: Penthesilea, In den Gängen, Harter Brocken, Notes of Berlin, Commercials and many more)

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

Cinematographer Matthias Bolliger (Known for: Miss Holocaust Survivor, Tatort, Boy 7, 4 Blocks TV Series and many more)

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.

Cinematographer Birgit Gudjonsdottir, BVK (Known for: Ein Wochenende im August, Tatort, In the Beginning There Was Light, Das erste Jahrhundert des Walter Alen and many more)

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.

1st AC Jake Marcuson (Known for: Dune, Solo: A Star Wars Story, Mary Magdalene, Rogue One: A Star Wars Story, The Take, Suffragette, Kick-Ass 2, Zero Dark Thirty and many more)

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