Aaton Penelope

Aaton Penelope is a 35mm motion picture camera introduced by Aaton in October 2008. It is the first camera in the world designed as a switchable Techniscope or 3-perf shooting solution (2 perf-native and 3 perf user-switchable), and it is also the first 35mm camera to offer a progressive scan video-tap. It accepts a digital magazine and therefore provide 4K digital output for true HD filming.

The Aaton Penelope is used by Scott Duncan to shoot the TV show Celebrity Apprentice, and cinematographer Hoyte van Hoytema has completed principal photography on The Fighter using Aaton Penelope cameras configured for 2-perf.
