Changing camera lens length in sculpting mode?

Is it possible to change the camera focal length in the sculpting mode? I’m trying to do a likeness and it would be great to sculpt at certain camera lengths to match references. You can do this in zbrush but its not as accurate as blenders normal cameras.

Is it not just the same setting as the 3D viewport focal length?

ViewportFocalLength

I could not find that! Thanks so much.
