Canon EOS R5 Mark IIvsCanon EOS R8: Full-Frame Pick
Both are full-frame Canon RF bodies with the same subject-detection autofocus list, a fully articulated screen and dust-and-drip sealing. The decision comes down to resolution versus size: the R5 Mark II gives 45 MP, in-body stabilization and 8K, while the R8 stays light at 461 g and shoots faster electronically.

Notes on 2 values — test conditions and caveats
- 1Canon EOS R5 Mark II, Pre-burst capture duration: Up to 15 shots can be buffered before you fully press the shutter, which is about half a second at 30 fps.
- 2Canon EOS R5 Mark II, Video codecs: Internal codecs are XF-HEVC S, XF-AVC S and H.264 MP4; ProRes RAW is recorded via HDMI to an external recorder.
Resolution and sensor
The R5 Mark II resolves 45 MP against 24.2 MP, and its stacked CMOS design reads out faster than the R8's conventional CMOS. That matters if you crop heavily or print large, because the extra pixels survive a hard crop and still leave room for detail. The R8's 24.2 MP is plenty for social, web and moderate prints, and the files are smaller and quicker to move.
In-body stabilization is the sharper split. The R5 Mark II stabilizes the sensor itself to 8.5 stops, which helps handheld shooting in dim light with any lens, including non-stabilized primes. The R8 has no IBIS at all, so handheld low-light work leans on lens stabilization or a faster shutter.
Burst speed and shutter
Electronic burst favors the R8: 40 fps versus 30 fps on the R5 Mark II. If you shoot fast action and can live with electronic-shutter tradeoffs, the cheaper body actually pulls ahead here. Both capture a 0.5-second pre-burst, so neither loses the moment before the shutter is fully pressed.
Mechanical shooting reverses it. The R5 Mark II does 12 fps and tops out at 1/8000 s, while the R8 does 6 fps and 1/4000 s. The faster mechanical shutter helps in bright light when you want to open the aperture wide, and the higher burst rate in mechanical mode keeps rolling-shutter distortion out of the frame.
Video
The R5 Mark II shoots 8K and records raw video internally. It also offers ProRes RAW, Cinema RAW Light and XF-AVC codecs, though ProRes RAW runs over HDMI to an external recorder. For anyone grading footage or delivering for cinema, internal raw is the single biggest reason to pay more.
The R8 stops at 4K, but 4K at 60 fps full width is where it holds its own; the R5 Mark II's 4K full-width figure is 59.94 fps, effectively the same. Both record 10-bit and both support log profiles, so the R8 is a credible video body unless you need 8K or raw. The R5 Mark II adds a full-size HDMI port, which survives repeated cable plugging far better than the R8's micro connector.
Viewfinder, screen and cards
The R5 Mark II has the better eye-level experience: a 5.76 M-dot viewfinder at 0.76x magnification against 2.36 M dots at 0.7x on the R8. A denser, larger finder makes manual focus and framing in bright sun noticeably easier. The rear screen is also higher resolution at 2.1 M dots versus 1.62 M dots, though the R8's 3-inch panel is fully articulated just like the R5 Mark II's.
The R5 Mark II carries two card slots to the R8's one. Two slots let you write a backup copy as you shoot or keep stills and video on separate cards, which is the practical difference for paid work where a single card failure ends the shoot.
Battery and size
Battery life runs 630 shots on the R5 Mark II against 370 on the R8. On a long event day that is the difference between one battery and carrying spares. Both charge and take power over USB, so a power bank can top either up between sessions.
The R8 is dramatically smaller and lighter: 461 g versus 746 g, and narrower, shorter and shallower in every dimension. It is the body you actually bring along, and the one that draws less attention. The R5 Mark II's bulk buys the bigger finder, dual slots and stabilization, but it is a bag decision, not just a spec-sheet one.
The Verdict
Buy the Canon EOS R5 Mark II if you need 45 MP, in-body stabilization, dual card slots and internal 8K or raw video for professional or high-end hybrid work. Buy the Canon EOS R8 if you want a light, compact full-frame body with the same autofocus coverage and 4K 60p, and you do not need IBIS or raw video.

FAQ
Do the Canon EOS R5 Mark II and EOS R8 use the same lenses?
Yes. Both use the Canon RF mount, so any RF lens fits either body. The R5 Mark II's in-body stabilization also means non-stabilized RF lenses gain shake reduction on that body only.
Which one is better for handheld low-light shooting?
The Canon EOS R5 Mark II, because it has 8.5 stops of in-body stabilization while the R8 has none. On the R8 you rely on lens-based stabilization or a faster shutter speed.
Do both cameras have the same autofocus subject detection?
Yes. Both list human, animal, bird, car, train, airplane and motorcycle detection, so autofocus subject recognition is not a reason to pick one over the other.
Is the EOS R8 better than the R5 Mark II for fast action?
Only in electronic burst, where the R8 reaches 40 fps against 30 fps. In mechanical burst the R5 Mark II leads at 12 fps versus 6 fps, and it also has the faster 1/8000 s mechanical shutter.
Can either camera record raw video?
Only the Canon EOS R5 Mark II records raw video internally. The R8 has no raw video option, and on the R5 Mark II ProRes RAW requires an external recorder over HDMI.
