Canon EOS R3 Mark II rumors are heating up following reports of prototype testing during the 2026 Milan Winter Olympics.
According to sources, the camera may feature the industry’s first dual native resolution stacked CMOS sensor, capable of switching between 54MP and 24MP modes depending on shooting needs.
Dual Native Resolution Sensor: 54MP and 24MP Modes
In 54MP mode, the EOS R3 Mark II is said to shoot at 40fps, while the 24MP mode pushes that to a staggering 90fps. The lower resolution mode reportedly uses an enhanced Bayer array that merges adjacent pixels, boosting sensitivity by approximately 80% compared to the original EOS R3. This sensor design could offer unmatched versatility for sports and wildlife shooters. For more coverage, see Canon EOS R3 II archive.
Autofocus & ISO Innovations
The rumored autofocus system uses a four-pixel CMOS AF design, with four photodiodes per pixel. This enables dual cross-type phase detection across all 54 million pixels — detecting motion horizontally, vertically, and diagonally. Triple native ISO technology is also expected, enhancing low-light performance and dynamic range. For broader Canon updates, visit the Canon rumors archive.
Video Capabilities: 9K RAW & 6K 120p
Video specs are equally ambitious. The EOS R3 Mark II may offer in-camera 9K 60p RAW and 6K 120p RAW recording, with full-pixel autofocus enabled during capture. These features would position the camera as a serious tool for high-end sports and documentary filmmakers.
Rumor Source & Skepticism
While Camera Beta claims to have seen the camera in Milan, Canon Rumors remains skeptical. The “FV120” label spotted in Canon CPS rooms likely refers to Firmware Version 1.2.0 for the EOS R1, not a hidden R3 II prototype. As always, take these specs with a grain of salt until official confirmation.
