Among the most anticipated camera releases on the horizon—including the Nikon Z7 III, Panasonic S1 II, Sony RX1R III, and Canon’s rumored retro-styled camera—the Canon EOS R6 Mark III is beginning to attract serious attention. While much of the buzz has focused on the Canon EOS R5 Mark II and the flagship EOS R1, the R6 III is expected to offer a compelling blend of features at a more accessible price point. But one question looms large: Will the Canon R6 III use the same sensor as the Canon EOS R3?
Latest Rumors: A Promising Spec Sheet
According to reports originating from Weibo and circulated by Canon Rumors, a source with a mixed record has shared a list of potential specifications for the Canon R6 III:
- Brand-new 24MP stacked CMOS sensor
- Readout speed somewhere between the EOS R1 and EOS R5 Mark II
- DIGIC X processor paired with a DIGIC accelerator
- Fully articulating LCD with an updated flippy mechanism
- Canon Log 2 and Log 3 support
- 6K RAW video at 60 fps
- 4K at up to 120 fps
If these specs are accurate, they indicate a serious leap forward in capability, especially for hybrid shooters and action photographers. The stacked CMOS sensor, in particular, suggests Canon is taking speed and responsiveness seriously—two areas where the EOS R3 has shined.
Will It Really Share the R3’s Sensor?
Previous reports have suggested that the Canon R6 III could borrow the sensor from the EOS R3, which is known for its excellent low-light performance, fast readout speeds, and robust dynamic range. For photographers and videographers working in unpredictable lighting conditions, this would be a huge advantage. But there are reasons to be cautious.
So far, only one source has made this claim, and no secondary confirmations have followed. While Canon has increasingly been known to share sensor architecture between models, especially in the RF mirrorless lineup, that alone doesn’t confirm the R3’s sensor will make it into the R6 III. It’s possible that Canon will instead debut a new 24MP stacked sensor tailored for this model—one that sits somewhere in performance between the R3 and the R5 Mark II.
Timing, Delays, and Strategic Positioning
Adding to the uncertainty is talk of a delay in the R6 III’s announcement, making it harder to pinpoint exactly what to expect. But this delay might also give Canon the opportunity to rethink its approach—especially after mixed reactions to the EOS R5 II and R1, both of which were seen by some as incremental upgrades rather than revolutionary steps forward.
Some critics even argued that the R5 II and R1 could have benefited more from firmware updates than full hardware overhauls. If Canon wants to regain trust and enthusiasm, the R6 III needs to go beyond simply refining its predecessor. It must address real user feedback and deliver features that stand out in today’s competitive landscape.
What Needs to Change from the R6 II
If Canon aims to make the R6 III a more convincing successor, several key areas need improvement over the R6 II:
- Competing cameras offer higher resolution sensors
- The learning curve remains steeper than other Canon models due to new features and interfaces
- Weather-sealing with older Canon flashes still requires a hot shoe adapter
- Exposure preview can occasionally hinder accurate in-camera exposure judgment
- The camera has grown heavier and larger compared to both the R5 and original R6
- Initial pricing for recent Canon cameras—such as the $6,000 R1—has caused sticker shock
If the R6 III can correct these issues while incorporating higher-end features like stacked sensor performance and advanced video specs, it could become a sweet spot in Canon’s full-frame lineup for both professionals and hybrid content creators.
Final Thoughts
Whether or not the Canon R6 III uses the R3’s exact sensor, it’s clear that Canon is aiming to push this camera closer to its high-end siblings. If Canon truly listens to feedback and delivers meaningful innovation, the R6 III could become a standout release in 2025. Until more sources confirm the sensor details, cautious optimism seems to be the best approach.
