Canon EOS R8 Mark II Review
The R8 Mark II keeps the R8's 24.2 megapixels and adds sensor-shift stabilisation and a deeper buffer at 40 fps. The single SD slot, the short battery rating and Canon's dust- and water-resistance rating stay.

The Verdict
The EOS R8 Mark II keeps the R8's 24.2-megapixel full-frame resolution and its 1,053-zone Dual Pixel CMOS AF II, then adds sensor-shift stabilisation, which the R8 never had, rated by Canon at up to 7.5 stops in the centre of the frame. The buffer at 40 fps holds 73 RAW frames against the R8's 56, with 20 frames of pre-capture. The body, mostly magnesium alloy, is listed as dust- and water-resistant, as the R8's is.
What did not change is just as specific: one SD UHS-II slot, a battery Canon rates at 340 shots on the screen and 220 through the viewfinder in power-saving mode, and no mechanical first curtain, so no fully mechanical shutter mode. For a first full-frame body that has to do stills and full-width 4K60 video, that is a sound set of trade-offs. For paid work that needs a backup copy on a second card, it is the wrong camera. Canon Germany gives 20 October 2026 as the availability date.

What Stands Out
- Sensor-shift stabilisation, which the R8 does not have at all
- A body that is mainly magnesium alloy, listed by Canon as dust- and water-resistant like the R8
- 4K60 across the full sensor width, oversampled from 6K; Full HD to 179.82p
- 40 fps with 73 RAW frames of buffer and 20 frames of pre-capture
- Autofocus rated down to EV −7.5, one stop below the −6.5 EV Canon gives for the R8
Trade-offs
- One SD slot: Canon lists dual card recording as "No"
- 340 shots on the screen and 220 through the viewfinder, already in power-saving mode
- No mechanical first curtain: the electronic first-curtain mode stops at 6 fps and 1/4000 s, and everything faster is fully electronic
- The 7.5-stop rating is measured with a stabilised lens; Canon gives no body-only figure
- 546 g with card and battery, 85 g more than the R8 by Canon's figures
In Depth
What the Mark II changes
Resolution does not change: 24.2 megapixels, 6000 x 4000 pixels, the same numbers Canon gives for the R8. The printed sensor size does: 36.0 x 24.0 mm for the Mark II, 35.9 x 23.9 mm for the R8. Canon does not say whether this is the same sensor or a new one, and a rounded dimension on a spec sheet is not evidence either way.
The changes are elsewhere. Sensor-shift IS, which the R8 lacks. The body is not one of them: Canon describes both as mainly magnesium alloy, partly aluminium and glass-fibre polycarbonate, and lists both as dust- and water-resistant. The 40 fps buffer grows from 56 to 73 RAW frames (190 JPEG), and pre-capture keeps the 20 frames before you fully press the shutter. The autofocus range extends to EV −7.5 under Canon's test conditions (f/1.2 lens, centre point, One-Shot AF).
Stabilisation: read the footnote
Canon's figure is "up to 7.5 stops" at the centre and 7.0 at the edges, to the CIPA 2024 standard. The footnote matters: Canon measured it with the RF 24-105mm F2.8 L IS USM Z at 105 mm, a lens with its own optical stabiliser, working together with the body. So 7.5 stops describes body plus IS lens. Canon publishes no number for the body on its own.
That does not make the IBIS less useful. The R8 has none, so with an unstabilised prime such as an RF 50mm f/1.8 nothing steadies the frame; on the Mark II the sensor moves. How many stops that buys with a given unstabilised lens is not something Canon states.
Speed: 40 fps on the electronic shutter
The R8 II has no mechanical first curtain, so there is no fully mechanical shutter mode. Canon lists two modes. Electronic first curtain runs at 6 fps, tops out at 1/4000 s and keeps going for more than 1,000 JPEG or RAW frames. The fully electronic shutter reaches 40 fps (20 fps in H, 5 fps in L) and 1/16000 s in Fv, Tv and M, with a buffer of 190 JPEG or 73 RAW. Canon's buffer figures are taken with a 128 GB UHS-II card at ISO 100 and 23 °C, and only RF lenses and some EF lenses reach the full speed.
Two things the spec sheet does not settle. Canon publishes no sensor readout time, so how much a fast subject or a fast pan skews in the electronic mode is not on paper. And Canon's own documents disagree on the AF mode behind the 40 fps figure: the spec page's footnote says One-Shot AF, the German press release says Servo AF. If continuous tracking at 40 fps is the reason you buy it, that is worth checking in a shop before you commit.
Video, cards and battery
4K UHD runs up to 59.94p across the full sensor width and is generated from 6K oversampling. A crop mode narrows the view to about 62% of the width, and Canon applies it automatically with RF-S and EF-S lenses. Full HD goes to 179.82p for slow motion, which needs an exFAT-formatted card and limits the shutter to 1/200 s at that rate. Clips can run up to six hours below 100 fps; Canon publishes no overheating times, only that overheating can stop a recording earlier. Canon Log 3 and HDR PQ are available, and the micro HDMI port outputs 10-bit 4:2:2 with either.
Everything is written to one SD slot. Canon recommends UHS-II cards for 4K and high-speed bursts. The LP-E17 battery is rated at about 340 shots on the screen and 220 through the viewfinder, both in power-saving mode at 23 °C, and Canon notes that accessories in the multi-function shoe draw from it too. The camera can charge the battery and run on power over USB-C; USB charging does not work with batteries it cannot authenticate. Plan on a second LP-E17.

Computed from the figures above. Pixel pitch = sensor width / pixel count across. Light gathered = log2 of the area ratio to 36 x 24 mm. Diffraction limit = the aperture at which the Airy disc diameter (2.44 x lambda x N, lambda = 550 nm) reaches two pixel pitches. Other calculators use other thresholds and so quote other numbers.

Recommended Accessories
Essential gear to maximize your Canon EOS R8 Mark II experience:
ProGrade Digital SDXC UHS-II V90 128 GB
There is one SD slot, Canon recommends UHS-II for 4K and fast bursts, and its 40 fps buffer figure is measured on a 128 GB UHS-II card.
Canon LP-E17
The battery the R8 II ships with. At 340 shots on the screen and 220 through the viewfinder, a spare is the first thing to add.
Canon RF 50mm f/1.8 STM
A small RF prime with no stabiliser of its own: on the R8 II the moving sensor steadies it, on the R8 nothing does.

FAQ
Does the R8 Mark II use the same sensor as the R8?
Canon does not say. Both are 24.2 megapixels at 6000 x 4000. Canon prints 36.0 x 24.0 mm for the Mark II and 35.9 x 23.9 mm for the R8, which could be a new sensor or a different rounding. Without a statement from Canon, neither "same" nor "new" is supported.
Does it have a fully mechanical shutter?
No. Canon lists electronic first curtain (up to 6 fps and 1/4000 s) and fully electronic (up to 40 fps and 1/16000 s), and states that the camera has no mechanical first curtain. If your work depends on a fully mechanical shutter, look elsewhere.
How long does the battery last?
Canon rates the LP-E17 at about 340 shots on the rear screen and 220 through the viewfinder, CIPA standard, power-saving mode, 23 °C. For comparison, Canon's screen figure for the R8 is 370. It charges over USB-C, but a spare battery is the practical answer for a full day.
R8 Mark II or R8?
The Mark II if you want stabilisation with unstabilised lenses or the deeper 40 fps buffer with pre-capture. The R8 if neither matters to you: both have 24.2 megapixels, 1,053 AF zones, full-width 4K60 from 6K, one SD slot and Canon's dust- and water-resistance rating, and the R8 is 85 g lighter. Our R8 II vs R8 comparison goes through the differences.
Final Recommendation
The R8 Mark II is the R8 with stabilisation added and a deeper buffer. What it keeps is Canon's dust- and water-resistance rating, one card slot and a battery you will want a spare for, and it has no fully mechanical shutter mode.
Buy it if: you want 24MP full-frame stills and full-width 4K60 in a light body, you shoot handheld with unstabilised primes, or you photograph unpredictable moments where 40 fps with pre-capture helps.
Skip it if: you need two card slots for paid work, you want a full day on one battery, or you need a fully mechanical shutter.
