Monochrone mastered

The new ALEXA XT B+W camera represents the state-of-the-art in digital monochromatic cinematography, and is the latest addition to the ALEXA family. It combines a modified ALEV III ALEXA sensor with all the features of the ALEXA XT (Extended Technology) camera range: in-camera ARRIRAW recording up to 120 fps, a 4:3 Super 35 sensor, LDS PL mount, new viewfinder mounting bracket and a new, super silent fan.

The ALEXA XT B+W sensor assembly has no Bayer mask, optical low pass filter (OLPF) or IR block filter, allowing each photosite to capture the full spectrum of visible light and upping the base sensitivity to 2000 ASA. Images from the camera are therefore sharper and display more contrast than those from a standard ALEXA with the color wound down, delivering rich, monochromatic images that display more contrast and increased spatial resolution, with 15 stops of dynamic range.

In addition to black-and-white, the camera can also be easily configured to capture infrared. In this mode the camera only 'sees' the reflected, infrared, non-visible light. Switching between these modes can be carried out effortlessly through the use of two new interchangeable internal filters - a BG39 filter for stunning black-and-white or a BG87C infrared pass (visible light block filter) for dramatic infrared.
