ARRI’s first new sensor in 12 years builds on the evolution of the ALEXA family over that period, delivering 2.5 stops more dynamic range, film-like highlight handling, better low light performance, and richer colors.
ARRI’s first new sensor in 12 years builds on the evolution of the ALEXA family over that period, delivering 2.5 stops more dynamic range, film-like highlight handling, better low light performance, and richer colors.
With its Super 35 4:3 native 4K sensor, the Alexa 35 can be used with an extensive array of lenses. Stray-light suppression in the camera and lens mounts ensures that the full contrast range and character of each lens are captured by the sensor.
With low noise and sensitivity settings ranging from EI 160 to EI 6400, Alexa 35 is a “High ISO” camera. An optional Enhanced Sensitivity Mode can be applied to settings between EI 2560 and EI 6400, producing an even cleaner image in low light.
Reveal Color Science is the collective name for a suite of new image-processing steps used by the Alexa 35 internally and also available through third-party postproduction tools for ArriRaw processing. It includes an improved Debayering algorithm for cleaner compositing, a new color engine for more accurate color reproduction, a new wide-gamut colorspace for faster grading, new LogC4 encoding to contain the increased dynamic range, and new LogC4 LUTs. Reveal is also backwards compatible. ArriRaw footage captured by Alexa LF and Mini LF cameras can be processed with Reveal, meaning the Alexa 35 and Arri’s large-format cameras can be combined on set and can also share LogC4 LUTs in post. 
Arri Textures is a new feature that allows cinematographers to fundamentally alter the way in which the camera records images. Until now, Alexa cameras have been preprogrammed with a default texture that determines the amount and character of grain in the image and the amount of contrast at different levels of detail (perceived by the viewer as sharpness). The Alexa 35 provides the option to choose from a menu of textures, much like selecting a film
stock.
A new set of mechanical-support items provides flexible options for any shooting situation, scaling quickly from a small and lightweight setup to a full-blown production configuration.
