The ARRI ALEXA 35 camera builds on the evolution of the ALEXA product line over the past decade, elevating digital cinematography to a new level. Thirty of the 49 films premiering at the 2022 Cannes Film Festival, including Palme d'Or winner "Triangle of Sadness," used ARRI ALEXA cameras powered by custom CMOS image sensors from ONSemi.

Onsemi announced on the 16th that it has developed a custom advanced CMOS sensor for ARRI's ALEXA 35 camera.

The new camera uses ON Semiconductor’s ALEV 4 Super 35 4.6K CMOS image sensor, which offers a resolution of 4608x3164 pixels (14.6 megapixels) with a 6.075um pitch, RGB color filters and a maximum frame rate of 120 fps. The sensor features ON Semiconductor’s latest technologies for optimized pixel response, HDR technology and improved pixel uniformity at high-speed readout, technologies also found in mainstream ON Semiconductor sensors.

The collaboration between Onsemi and Ari demonstrates Onsemi's strengths in developing advanced imaging sensors that enhance image quality. This unique high-resolution, large-pixel image sensor, featuring optimized readout technology, delivers 4.6K images at 120 frames per second and 17 stops of dynamic range, producing images of unprecedented quality. The extended dynamic range enables greater detail in high-contrast scenes within a single frame, delivering a superior image and color experience.

“All digital ARRI cameras, starting with the first ARRIFLEX D-20 in 2005, through the first ALEXA in June 2010, and up to the ALEXA 35 launched this year, are based on CMOS sensors developed jointly with ON Semiconductor,” said Walter Trauninger, Managing Director and Head of ARRI’s Camera Systems Business Unit. “The close collaboration between our two companies lays the foundation for providing filmmakers with the highest image quality possible. This long-term commitment is an absolute exception in the constantly changing semiconductor market and is extremely important to us.”

“Working with ARRI to develop the image sensor for the Alexa 35 camera demonstrates ON Semiconductor’s ability to develop high-quality, advanced sensors at a low cost while maximizing performance,” said Ross Jatou, vice president and general manager of ISG at ON Semiconductor. “Our close collaboration with ARRI for 22 years demonstrates Onsemi’s commitment and technology to providing image sensors to the advanced digital cinematography and machine vision markets,” he said.

With Onsemi's ALEV 4 CMOS image sensor, ARRI is elevating the state-of-the-art camera by providing superior image quality, natural colors, and an entire ecosystem for the global film industry.

Meanwhile, in 2017, the Arri Alexa camera system, featuring Onsemi's CMOS sensor, won a Scientific and Engineering Award from the Academy of Motion Picture Arts and Sciences (AMPAS) and an Engineering Emmy from the Television Academy.
