According to Canon Rumors, the Canon EOS R3 Mark II has reportedly been spotted in testing at the 2026 Milan Winter Olympics. The camera is said to feature the industry’s first dual native resolution back-illuminated stacked CMOS sensor, capable of switching between 54MP and 24MP modes.
The rumored specs come from a Chinese social media account called Camera Beta. In 54MP mode, the camera can reportedly shoot at 40fps continuous, while the 24MP mode pushes that to a blistering 90fps. The 24MP mode uses an enhanced Bayer array that merges adjacent pixels, boosting sensitivity by about 80% over the original EOS R3. Triple native ISO tech is also part of the package.
On the autofocus side, it’s said to use a four-pixel CMOS AF system with four photodiodes per pixel — dual cross-type AF across all 54 million pixels, with phase detection working horizontally, vertically, and diagonally. Video specs are equally wild: in-camera 9K 60p and 6K 120p RAW recording with full-pixel autofocus.
That said, Canon Rumors is skeptical. The editor notes that photographers at the Milan Olympics haven’t seen any hidden R3 II prototypes, and the “FV120” label spotted on Canon CPS room shelves likely just means Firmware Version 1.2.0 for the EOS R1. Take these specs with a healthy grain of salt for now.
