class="style16"> Flange Distance For Red

Published : 30th August 2009


I'm just starting to work with Red and I don't quite understand how the lenses should be set up. The rental house I am dealing with has several sets of lenses (16mm & 35mm lenses) and they are in the habit of adjusting the backfocus on the camera body every time they change lenses.

>Is this is right way to set up the lenses on a Red? Is there a standard flange setting for the Red (as there is with Arri and other cameras)?

Where can I find that information?

Here is my 2 cents, think of the Red like a film camera, and movie PL mount lenses are no different. Lenses are standard 52mm.?


We check the Red with a shop perfect test lens and a auto collimator. ?Once the depth is set if any other lens doesn't look right it is put on a bench collimator and projector to? Calibrate.


Sounds like those lenses need some work.

Egon,


That's what I thought. But I was a little unclear it the 52mm held true for 16mm lenses if you are shooting in 2K.
Thank you!

The RED should be set up the same way that a 35mm camera is and then left alone.
In 10 weeks shooting with 2 cameras we had the cameras set-up at the start of the shoot and then just used them.


I seem to recall that we had to swap out one body because it wasn't collimated properly but apart from that we just changed lenses as we normally would.
