Canon’s EOS R5 series has established itself as a flagship hybrid camera, seamlessly serving both photographers and videographers with a remarkable blend of performance and flexibility. With the EOS R5 Mark II still fresh on the market, it may seem premature to talk about a Mark III. But if Canon’s development cycle remains consistent—releasing a new model every three to five years—we’re realistically looking at a potential R5 Mark III launch between late 2027 and mid-2028.
That timeline may sound distant, but it’s precisely why the conversation needs to start now. Once Canon finalizes its design and specifications, it’s often too late for user feedback to make a meaningful impact. As a working photographer and videographer, and based on countless conversations with fellow creatives, here’s what I believe Canon needs to consider for the next evolution of this beloved camera.
1. Sensor Speed—Without Sacrificing Quality
The R5 Mark II gave us a much-needed speed boost with its stacked sensor, reducing rolling shutter from 16.3ms to 6.3ms. However, the Canon EOS R1 is already pushing further with a readout time of 2.7ms—even without a global shutter.
For the R5 Mark III, Canon should aim for similar or better performance, not just through sensor speed, but by enhancing components like the photoelectric conversion layer, analog amplifier, and image processor. Faster readout is crucial for action, sports, and fast-moving subjects, but not at the expense of dynamic range and high ISO performance.
While a global shutter would be ideal, even achieving near-zero rolling shutter with excellent noise control and shadow detail would be a significant win for the vast majority of users.
2. Autofocus That Understands the Scene
Canon’s use of a dedicated DIGIC Accelerator chip in the R5 Mark II significantly improved predictive subject tracking. But performance still stumbles in cluttered environments—branches, grass, and dimly lit scenes can confuse the system.
The next generation of autofocus needs to be smarter, not just faster. Canon should leverage machine learning more aggressively, allowing the system to better recognize subject context. Whether it’s a bird in flight, a sprinter on the track, or a vlogger in a studio, the camera should adapt intelligently to what’s in front of it. Other manufacturers, like Nikon, are already moving in this direction. Canon can’t afford to fall behind.
3. Internal ND Filters—Long Overdue
Canon has filed numerous patents (JP 2023-12853, 2023-128236, 2023-129247, among others) for internal ND filters compatible with existing R5-style bodies. Yet, this much-requested feature remains absent.
Adding built-in ND filters would be a game-changer—eliminating the need to screw on filters, reducing weight, and streamlining workflow. For run-and-gun videographers, travel shooters, and anyone filming outdoors, this is a practical upgrade with massive usability benefits.
4. Pixel Shift, Reimagined
Sony’s A7R V delivers 240MP pixel shift images, even accounting for movement in the scene. Canon’s earlier pixel shift efforts fell short, and the AI upscaling feature in the R5 Mark II doesn’t fill that gap—it often creates results that feel processed rather than precise.
Canon should revisit pixel shift with motion-aware AI correction, not AI generation. For food, product, and architectural photographers, this could unlock unparalleled detail—without resorting to artificial enhancement.
5. Better High ISO Performance—Stop the Regression
It’s troubling to hear that some photographers feel the original R5 outperforms the R5 Mark II in high-ISO, low-light conditions. Despite the R5 II’s newer stacked sensor, some users report increased noise levels at higher ISOs.
This needs to be a wake-up call. A 45MP stacked sensor should, in theory, bring gains in both speed and sensitivity. For the R5 Mark III, Canon must focus on sensor design that improves ISO performance and dynamic range without compromise.
6. Tilting EVF—Time to Deliver
Canon has been rumored to be working on a tilting electronic viewfinder, and now Sony has beaten them to the punch with the FX2. For photographers who shoot at awkward angles or in challenging environments, this seemingly small ergonomic change would be deeply appreciated.
7. 32-Bit Float Audio Recording
Audio is a critical part of video, and 32-bit float recording could drastically simplify the process. It allows videographers to capture whisper-quiet and ear-splitting moments without manual gain adjustments or fear of clipping.
Canon could implement this via a new hot shoe XLR module or dual ADCs built into the camera. Brands like Panasonic and Fujifilm already offer this. Canon should follow suit, especially if they want to stay competitive in the hybrid space.
8. A Bigger, Better Battery
The LP-E6 series has served Canon well, but it’s now holding back video capabilities. Even the upgraded LP-E6NH struggles with battery life and heat management during extended high-resolution or high-frame-rate recording.
The R5 Mark III should introduce a new battery format with higher capacity and better thermal performance. Creators need reliability and endurance—not workarounds.
9. Dual CFexpress Type B Slots—Enough is Enough
One CFexpress Type B slot paired with an SD slot isn’t cutting it anymore. It forces creators to micromanage media and limits the camera’s high-end features when using the slower SD slot.
It’s time Canon moved to dual CFexpress Type B slots. This would bring the R5 Mark III in line with professional expectations without cannibalizing the R1, which still targets a different audience.
10. Quiet Active Cooling
No, the R5 Mark III doesn’t need to be the R5C. But a silent internal fan that only activates when needed could make a world of difference—especially for extended 8K or 4K120 recording sessions.
Canon could take inspiration from cinema cameras: fans that disengage during active recording and kick in quietly between takes. This small addition could make overheating a non-issue.
11. Resolution and Frame Rate Expectations
If Canon truly plans to discontinue the R5C line, the R5 Mark III will need to carry the video torch. At a minimum, we’d like to see:
- 8K 60fps RAW recording
- 4K 120fps with full sensor readout and no pixel binning
- FHD 240fps, ideally with sound
These features are no longer outlandish requests. With RED tech likely integrating into Nikon, the pace of innovation is accelerating. Canon must match that momentum.
12. Why Now Is the Right Time to Speak Up
Canon typically finalizes camera specifications 12–18 months before launch. That means that even though we may not see the R5 Mark III until 2028, decisions about its hardware and features are likely happening now.
If you care about the direction this camera takes, let Canon know. Share your thoughts in forums, at trade shows, in feedback forms, and yes—even in YouTube comments. The R5 isn’t just Canon’s camera—it’s ours too. And this is our chance to help shape its future.
Closing Thoughts
The Canon EOS R5 Mark III has the potential to be more than just a minor upgrade—it could be a generational leap for hybrid shooters. But only if Canon listens. This wishlist reflects real-world needs from real users. It’s time for us to raise our voices and ask for the features that will genuinely improve our creative work.
Let Canon know what matters to you. The clock is already ticking.
