RED ONE MX 4.5K film back measurement

[Russell Dodgson]

Hi guys,

Just sitting down to 3d track a shot and realised i don't have the film back measurement sofr the REDONE MX when shooting at 4.5k (yielding a 4480 x 1920 image).

I have been searching around but seem to find different answers.

I usually refer to a sensor size chart, but it seems that this format is not on there.

Big thanks to anyone who has a concrete answer

cheers

Russ

I think you just multiply the pixels by .0054 to get the dimensions, so that gives me 24.19mm x 10.37mm if you are recording 4480 x 1920.

Hey Russell!

This is what I found:

Note RECORDABLE AREA and actual sensor size are two different things. The MX sensor is the same as in the new Epic cameras, ie 5K, and bigger than the M sensor (same pixel pitch), but due to electronics limitations not all of it is usable - ie limited to 4.5K.

Best way to figure is as David points out above. Pixels on both the M and MX sensors are 5.4 microns squre. Or 0.0054mm in size. So if you multiply your pixel dimensions of the mode you're shooting in by 0.0054, you will get the size in mm.

Having gone through all the pages linked in my post above, David ( as usual ) is spot on with his 24.19mm x 10.37mm dimensions! :smile:
