Is there a way to match the area of the Camera at different Camera Focal Length?
Im not sure i understand the question. Do you have a refference example?
Can’t think of a way to show this and almost sure this can’t work but want to change the focal length of the Camera having the same part / amount of the scene in view.
Sounds like you want to create a vertigo effect? In that case you can animate the position and focal length of the camera like so:
Yes but that’s done manually. Also, there are strange misalignments.
