I upgraded from the R to the R5.
- Canon EOS R5 Mark II:
- Electronic Shutter: Up to 30 fps (frames per second) with full AF/AE tracking.
- Mechanical Shutter: Up to 12 fps.
- Electronic 1st-Curtain Shutter: Up to 12 fps (same as mechanical).
- Customizable lower speeds: 20, 15, 10, 7.5, 5, 3, 2, or 1 fps.
- Canon EOS R1:
- Electronic Shutter: Up to 40 fps with full AF/AE tracking.
- Mechanical Shutter: Up to 12 fps (same as R5 II).
- Note: The R1 is designed for speed, making its 40 fps capability a significant advantage for sports and action photography.
- Buffer Capacity
- Canon EOS R5 Mark II:
- Electronic Shutter (30 fps):
- JPEG/HEIF: Up to 200 frames.
- RAW: Up to 93 frames (CFexpress card) or 86 frames (SD card).
- Mechanical Shutter (12 fps):
- JPEG: Up to 760 frames.
- RAW: Up to 230 frames (CFexpress card) or 95 frames (SD card).
- Real-world buffer performance depends on memory card write speeds (CFexpress Type B clears faster than UHS-II SD).
- Canon EOS R1:
- The R5 II's Pre-Continuous Shooting mode captures 15 frames (0.5 seconds at 30 fps) before the shutter is fully pressed, while the R1 captures 20 frames (0.5 seconds at 40 fps).
- Buffer and fps can vary based on settings (e.g., ISO, file format, lens used, battery type).
So the R1 is a bit faster in most ways, at the cost of resolution. I will say it's tough going back to lower res cameras for certain situations, especially since all the RF lenses can handle a ton of resolution- Electronic Shutter (40 fps):
- JPEG/RAW: Over 1000 frames, effectively near-unlimited for most practical scenarios.
- The R1's buffer is significantly larger, designed for sustained high-speed shooting, making it ideal for professional sports and wildlife photographers.
Both cameras use CFexpress Type B and UHS-II SD card slots, but CFexpress cards are recommended for maximizing buffer performance.And no, you can't use AI to capture action on the court in a way you can with a dedicated camera.
Other photography professionals have other needs. Some need high megapixels, or other needs. This is a specialized tool for a very few number of people.
I upgraded from the R to the R5.
The built-in vertical grip allows for better ergonomics (often all the buttons for horizontal shooting are there for vertical too, additional grips don't do that 100%). More importantly, it comes with a massive battery that outlasts the 2x batteries you can fit on the 5-series + battery grip combo, often by a large margin.
You also get a faster mech shutter with 1/250 x-sync on the R1 over 1/200 on the R5 II, but electronic shutter does better for both I think. Useful if you are shooting outdoors with strobes for fill etc.
During the DSLR era, the 1 series would also have a much higher effective shutter life - when all actuations were through the mechanical shutter, that was a "consumable" for many pros would decommission your tool waiting for a replacement part.
Now, these differences would be far more pronounced if you were talking EOS 1Ds III vs 5D II etc. Now that the "R5 II" is like 50% more expensive than the DSLRs and more and more shit is fully electronic, many of the differences, especially during electronic shutter operation, are muddied up.
If you calculate the MP throughput of the top "high MP sensor" model and the 1 series "High FPS" model, you can see that it is often comparable and you just trade MP for individual photos, with the ability to shoot a gazillion frames and pick the one that the ball is on the exact spot yo uwanted or the bird splashes off the waves exactly when you wanted etc, all of which - for some people - look good enough with 20MP sensors.
The High MP alternatives are better for single-shot operation where you care about fine details more, are much lighter if you don't care to lug around the battery for the 2,000 frames and whatnot, or you don't mind shifting your wrist a bit further when shooting vertical frames. The vast majority of shooters need neigher more than 30MP or super-high FPS.
