Quote - You can do that without Python with a simple Ctrl-c on the camera and CTRL v on the camera you want to copy it to.

This wouldn't work directly with any camera when I tried it on Poser 7 - maybe it's changed in later versions?

If you paste the settings into Notepad or similar, you can see that they include the camera name and hence will only apply to that camera. I did manage to "hack" it by search-and-replacing the camera name string before pasting back in. I was going from Aux to Main IIRC, or possibly vice-versa.
