The broadcast TV projection room is designed to test 4K cinema lenses, which need to deliver sharp performance from corner to corner at every aperture and focal length. Appropriately, the design of this room is all about precision.

Although you can't see it in the dark, the testing hardware is mounted on a rail system that is precisely aligned to the projection wall. In fact, Canon told us that its engineers, along with the construction firm, spent over a week just building the projection wall to ensure that it was perfectly vertical and without imperfections.

Targets projected through a lens allow technicians to calibrate for sharpness, color, flare, and uneven focus. The target in this photo is a generic pattern to demonstrate the equipment; Canon assures us that it has proprietary targets that are used when calibrating lenses.
