Redrock Micro Sonar Auto Focus System

We shot this as a one-shot with a wide-open Zeiss 35mm at f2 and 5D MKII on a MōVI M5. As an early technology proof, it was a bit quirky but I was blown away by its performance. It differs from something like the Canon dual pixel AF, because it works in any lighting (including backlight or darkness), it doesn’t require a face to focus, and it’s super fluid and organic.

I don’t think it will completely replace focus pullers, but in situations where you want to use wide open lenses and selective focus, or if its not in the budget, this device is a perfect solution because it solves the focus issue without having to ditch the MōVI altogether. I found it super useful for any filmmaker, but I think it will be especially useful for gimbal operators.

This was a proof of concept technology, so I don’t know what will be the final technical details and specs. It definitely won’t replace focus pullers on large productions because in my opinion a seasoned AC will do a much better job at pulling focus, especially with creative shots with multiple subjects. Im Super excited to see where this concept prototype goes.

It was just announced that the new version of the device will be released at NAB 2015, and I will be answering questions about the video at their booth!
