Onsemi has just released a press release regarding the new sensor of the ARRI ALEXA 35. Onsemi declares that it has developed the new ALEV 4 sensor. Onsemi has been developing these magnificent ARRI sensors for more than 22 years, starting with the ARRIFLEX D-20, and continuing with the ALEXA 35. 

ALEV 4 was developed by Onsemi

Onsemi, the American semiconductor supplier company, today announced it developed the customized high-end CMOS sensor for ARRI’s ALEXA 35 camera. As stated by Onsemi: “The camera (ARRI ALEXA 35) uses the ALEV 4 Super 35 4.6K CMOS image sensor from onsemi to deliver a resolution of 4608×3164 pixels (14.6 Mpixel) with a 6.075 um pitch featuring RGB color filters and a maximum frame rate of 120fps. The sensor features onsemi’s latest technology for optimizing pixel response, High Dynamic Range techniques (HDR) and the improvement of pixel uniformity while reading out at high speeds; techniques deployed in mainstream onsemi sensors as well”.

ARRI & Onsemi: 22 years of partnership

“Developing the image sensors for the ALEXA 35 camera with ARRI shows our ability to develop high-end sensors that are low cost and high quality while maximizing performance”, said Ross Jatou, senior vice president and general manager of ISG at onsemi. “22 years of working closely with ARRI demonstrates our commitment and skillset to deliver image sensors for the high-end digital cinematography and machine vision markets”. In 2017, the ARRI ALEXA camera system with onsemi’s CMOS sensor was recognized with a Scientific and Engineering Award from the Academy of Motion Pictures Arts and Sciences and an Engineering Emmy from the Television Academy. Now, this tradition and strong partnership continue with full strength.

From ARRIFLEX D-20 to ALEXA 35

“All digital ARRI cameras—starting with the first ARRIFLEX D-20 in 2005, followed by the first ALEXA delivered in June 2010 up to the ALEXA 35 introduced this year—are based on CMOS sensors jointly developed with onsemi,” said Walter Trauninger, managing director and head of business unit Camera Systems at ARRI. “The close collaboration between the two companies is the foundation for ARRI’s ability to provide the best overall image quality to filmmakers. This kind of long-term commitment is an absolute exception in an ever-changing semiconductor market and is invaluable to ARRI.” Furthermore, as stated by Onsemi: “The ARRI ALEXA 35 camera elevates digital cinematography to new heights, building on the evolution of the ALEXA family over the last decade-plus. During the 75th annual Cannes Film Festival in 2022, 30 of the 49 films that premiered at the festival, including Palme d’Or winner “Triangle of Sadness,” used a camera from ARRI’s ALEXA family, all powered by onsemi’s customized CMOS image sensors”.

“Sensors for high-end cinematography”

Furthermore, Onsemi elaborates and says: “This latest collaboration between the two companies is another example of onsemi’s strength in developing sensors for high-end cinematography that elevate image quality. This unique high-resolution, large-pixel image sensor with optimized readout techniques result in a 4.6K image, 17-stops of dynamic range at 120 frames per second, producing images with unprecedented quality. The extended Dynamic Range enables higher detail in a high contrast scene in a single frame, resulting in an extraordinary image and color experience”.

Summary

This partnership which leads to a perfect business synergy between the two companies — ARRI and Onsemi, seems to continue with full strength. From the ARRIFLEX D-20 to ALEXA 35, Onsemi and ARRI are developing and defining the industry standards for high-end imagery. The acclaimed ALEV 3, and the newly announced ALEV 4, are no less than masterpieces in engineering that help to create fine art on our beloved big screen. Is ALEV 5 in the oven?
