DoP Philip Bloom introduces the long-awaited prototype EX3 1/2" Relay for the Letus line of DOF adapters in this video from CVP.com, the European distributor of Zacuto products.

In the video, Bloom demonstrates how to utilize a fixed focal length lens to control depth of field, while the exposure can be adjusted using the iris feature on the Letus 1/2” Relay lens. He also highlights the field of view difference between 35mm still cameras and 35mm movie cameras. The Letus 1/2”Relay adapter is designed to crop the image plane for the Academy format, which allows for the use of PL lenses without vignetting. Bloom says that the Letus EX3 1/2” Relay makes you feel as if you’re operating a 35mm camera. “It feels like a proper camera,” Bloom says, “and more importantly, it operates like a proper camera.”
