Interesting.

The word 'pan', came to me from using 3D CAD software and I considered the Jib and Truck actions as 'pan' and the original Pan would be camera rotation, which might be 'turn' (didn't use it as much so don't remember) which was less favourable than using 'orbit'.
Good to know the word origin.

Oh and btw, Dolly would not be zoom, but 'walk'.
