Setting Camera Frame Width from script

Hi there,

I have a script that instantiate a new camera , position it and sets up the focal length and frameWidth( see exmple below)

cam.focalLength=20.78461;
cam.frameWidth=24;

The focalLength works fine, but the frameWidth isn't getting set.... after digging more into the docs I see that frameWidth is a read only attribute which explains why I can't set it. However, I assume there is another way around it just can't find any function that can do that.

Hopefully someone here knows the answer to that.

Thank you.
