Zoom vs tracking

Identify the camera movement

This is a track-in shot.

The zoom, with its variable focal-length, was invented in 1949 by the optical engineer Roger Cuvillier – then aged only 27.

This optical compensation lens, sold under the Pan Cinor trademark, was presented at the “International Congress on Film Techniques” in 1950 in Milan. It was so successful that the Swiss company Paillard-Bolex proposed it for a series of its movie cameras.

Manufactured in Dijon, it was exported worldwide in the 1950s. In 1956, Pan Cinor was overtaken by Pierre Angénieux’s Zoom fitted with a mechanical compensation system. "Zoom" was thus initially the commercial name for the variable focal-length lenses created by Angénieux.
