The Canon EOS R6 Mark II is still a favorite among bird and wildlife photographers, but its successor—the Canon EOS R6 Mark III—is already generating serious buzz.
Based on credible leaks and early reports, Canon is preparing to launch the next-generation model, potentially as early as May 2025. But is this upgrade truly worth the wait?
Here is one review by Technologies.
In this post, I’ll explore the key rumored features, what they could mean for your birding photography, and how the R6 Mark III stacks up against the newly released Canon EOS R5 Mark II and the flagship Canon EOS R1.
A Faster Sensor Built for Action
One of the most exciting updates is a new 24MP stacked CMOS sensor. If true, this means faster readout speeds, reduced rolling shutter, and quicker continuous bursts—ideal for tracking small, fast-moving birds in flight.
Still, 24 megapixels might disappoint those who expected a resolution jump. Canon appears to be focusing on speed and reliability over sheer image size, which may benefit action photographers more than landscape or crop-happy shooters.
Smarter Autofocus and AI—A Game-Changer?
Rumors suggest the R6 Mark III will inherit the subject-priority autofocus system from Canon’s pro-level cameras, including improved tracking for animals and birds. There’s also talk of a DIGIC Accelerator processor that introduces AI-powered noise reduction and in-camera image upscaling—potentially boosting resolution to an effective 96MP.
While that sounds exciting, for bird and wildlife photographers should be cautious. AI enhancements can be hit or miss, especially in nature photography, where fine feather detail and natural textures are key. Until it’s tested in the field, experts approach these AI tools as “nice-to-haves,” not must-haves.
Dual Card Slots and an OLED Upgrade
Storage and usability are also getting attention. Expect dual card slots—CFexpress Type B + UHS-II SD—to support high-speed bursts and large video files. This is a welcome addition for birders who shoot in RAW or film high-res clips on the fly.
The rear screen may also see a redesign, with a dual-axis OLED panel offering improved tilt and articulation for awkward shooting angles. Whether you’re lying low for shorebirds or looking up in dense woodland, better flexibility is always a plus.
Canon R6 III vs R5 II vs R1: Which Should You Choose?
Now that both the Canon EOS R5 Mark II and Canon R1 are out in the wild, it’s easier to contextualize the R6 III’s place in the lineup.
Canon EOS R5 Mark II: With a 45MP stacked sensor, lightning-fast autofocus, and stunning detail retention, this is now the best high-resolution hybrid camera in Canon’s lineup. For birders who crop often or shoot both stills and 8K video, it’s a phenomenal choice—though you’ll pay for the power (around $4,000 USD).

Canon R1: Built like a tank, the R1 brings global shutter, blackout-free bursts, best-in-class AF, and unmatched reliability in the field. But it’s a true flagship with a $6,299 USD price tag, designed more for elite wildlife pros and sports shooters than average hobbyists.

Canon R6 Mark III (coming soon): With its expected 24MP stacked sensor, smart AF, and AI features, it’s shaping up as a speed-focused, field-friendly workhorse. Ideal for bird and wildlife photographers who don’t need ultra-high resolution but demand fast, dependable performance.
So, if you need maximum resolution, go for the R5 II. If budget isn’t a concern and you shoot under tough, fast conditions, the R1 is the king. But if you’re looking for a powerful, agile tool for everyday birding, the R6 Mark III may hit the sweet spot.
Release Date and Pricing of the Canon EOS R6 Mark III
Canon hasn’t made it official yet, but multiple sources hint at a late May 2025 release window. Pricing is expected to rise above the R6 Mark II’s original MSRP—potentially over $3,000 USD. At that price point, you’re bumping up against the Canon EOS R5 Mark II, which may be more appealing for high-resolution needs.
Should You Wait or Buy Now?
Here’s the bottom line: If your current gear is getting the job done, hold tight and see how the R6 Mark III performs in the wild. The new features sound promising—especially for fast-action birding and hybrid still/video use—but early specs don’t always tell the whole story.
If you’re eager to upgrade now, the Canon EOS R6 Mark II remains an excellent choice—and likely to see price drops soon.
Also, the R5 Mark II is an outstanding birding option.
Final Thoughts on Canon EOS R6 Mark III for Bird and Wildlife Photographers
The Canon EOS R6 Mark III looks like a thoughtful, performance-focused update for bird and wildlife photographers—but not necessarily a revolutionary one. If you already own an R6 Mark II or similar camera and it still serves you well, it’s worth waiting to see how the R6 Mark III performs in the field. The promised speed and AI features sound intriguing, but nothing revolutionary enough—yet—to justify ditching what works.
The Canon EOS R6 Mark III borrows speed and smarts from the R3 and R1 but likely keeps things more compact and approachable for everyday birders.
Still, in a lineup that now includes the formidable R5 Mark II and the powerhouse R1, the R6 III has to prove its worth by offering real-world speed, accuracy, and dependability at a fair price.
