Thanks guys for all your help.
But I think I'm confused now. There's conflicting answers in here I believe.
Randy says the lens is as is with a constant film back size (22.2mm x
12.6mm), while Misho says I should use 0.96 conversion for the lens.
Basically it's a Red One shooting 3K with an 18mm
I didn't say it was constant, I gave the size for shooting 4k. The
lens focal length is constant as long as the mount is to spec for the
given mount. and by constant I mean the focal length of a lens
doen't change with the amount of image plane being used. So a 25mm is
a 25mm (sort of)
Hi all,
Here you have a handy website I recently found.
It will give you a filmback for each setting. 3k, 3k ana, 4k etc. for
different camera's

But won't I need to change the size of the film back?

I haven't.
I get what you're saying. That makes sense.
Thanks everyone!
I should really get my head around all this projection / field of view
stuff. Anybody has a good resource?

Hi all,
needing to cam track some Red footage. Anybody knows what the film back is,
and if I should change the focal length to compensate for a different size
film back?

It depends which red and which resolution it was shot at. The Red One
crops the sensor to shoot at different resolutions(4.5k, 4k, 3k, 2k).
If you have 6.3 I have them all in my camera presets here:

The Red can capture footage in a variety of ways, 4K 16:9, 2K 16:9 etc, and
they all crop the sensor in different ways. To find out what sensor size you
should use, just multiply the pixels of your image by 0.0054 (the size of
the pixels on the sensor in mm).
For example, if the camera captured
