Cinema camera focal length incorrect?
Hi, I am not sure if this is a bug, or if I am missing something...
I am trying to match some real camera footage with an augmented overlay in unreal.
I set the cinema camera up to match the settings of the real camera. Object distance, film back and focal length, and it doesn't line up.
The weird thing is, if I double the focal length value, it works perfectly.
I have tried this with different cameras and lenses, and see the same results.
Should this be working? Or is there an equation to get from ue 'focal length' to real world focal length?

I wanted to update you on this. I ran a test yesterday shooting with a Super 35 camera and a 24-200mm lens (shot at 24mm) and I'm noticing some discrepancies with the cine cameras. We'll be continuing our tests on this, but it might be a slow process.

Are you using the "Super 35mm" drop-down on the CineCamera, or are you setting the Sensor width/height manually to 22mm x 11.8mm? I ask because the measurements we are using for Super 35 are 24.889mm x 18.66mm.
If I create a camera in Maya with a filmback of 22mm x 11.8mm and a focal length of 24mm I get identical output when compared to a CineCamera with the same settings.
