Review: Canon EOS R5 Mark II – The Full-Frame Camera That Doesn't Compromise

The Canon EOS R5 Mark II launched in 2024 at 4 299 USD. It sits in the high-end versatile full-frame mirrorless segment, between the R3 (5 999 USD, 24.1 MP, pure sports) and the R5 C (4 499 USD, 45 MP, cinema-oriented). The Mark II targets photographers who refuse to specialise.

The move to a Stacked CMOS sensor (36 × 24 mm, 45 MP) is the major technical break from the first R5. A stacked sensor integrates buffer memory directly on the chip, speeding up data readout. Direct result: electronic burst rises from 20 fps (original R5) to 30 fps, and rolling shutter, the Achilles heel of conventional CMOS sensors in electronic mode, drops significantly. This is not cosmetic: it is what makes electronic burst usable on fast-moving subjects.

On the current market the R5 Mark II faces two direct rivals at comparable resolution: the Nikon Z8 (45.7 MP, Stacked CMOS, 4 000 USD) and the Sony A7R V (61 MP, conventional BSI CMOS, 3 900 USD). Canon sits between them on price, above on electronic shutter speed (1/32 000 s) and IBIS (8.5 stops versus 8 stops for the Z8 and Sony). The question is not whether it is good. It is whether it is worth 300 USD more than the Z8 for your specific needs.

OLED viewfinder and fully articulated screen

The OLED viewfinder reaches 5 760 000 dots at 0.76x magnification. It is the class reference: the Nikon Z8 shows 3 690 000 dots and the Sony A7R V 9 440 000 dots, but the latter weighs 723 g and drains more battery. In practice 5 760 000 dots are ample for checking focus on moving subjects. Fluidity matters as much as raw resolution, and the R5 Mark II viewfinder is flawless on this point according to independent DPReview tests.

The 3.2-inch (2 100 000-dot) screen is fully articulated. This complete hinge, absent on the Nikon Z8 (tilting only), is a real advantage for solo video and low-angle shooting. The screen is touch-sensitive, allowing AF point movement without taking your eye from the viewfinder via touch-in-EVF mode.

Eye Control AF: the polarising feature

The R5 Mark II reintroduces Eye Control AF, a technology that tracks the photographer’s eye movement through the viewfinder to place the AF point. Canon dropped the feature after its 1990s film EOS bodies. Its return has divided specialist opinion: repaire.net notes that calibration can be inconsistent depending on eye shape and ambient light. The function is useful for sports or reportage shooters who want to select a zone quickly without touching the joystick. It is optional and can be disabled. Do not buy for this feature alone: treat it as a bonus whose reliability varies from user to user.

Dual slots and connectivity

The dual CFexpress Type B and SD UHS-II slot configuration is serious. CFexpress Type B provides the bandwidth needed for sustained 45 MP RAW bursts. The SD UHS-II slot in second position is a pragmatic compromise: SD cards remain cheaper and more widely available than CFexpress for backup or quick field transfers. USB-C 3.2 Gen 2 supports high-speed transfer and body charging. The full-size HDMI output is a plus for videographers connecting an external monitor without an adapter.

Measured dynamic range and high-ISO noise

Dynamic range measures 11.5 EV at base 100 ISO according to our verified database, aligned with Photons to Photos data. This is an honest result for a stacked sensor: Stacked CMOS generally sacrifices fractions of an EV in dynamic range versus conventional BSI sensors in exchange for readout speed. The Sony A7R V (BSI CMOS, 11.7 EV) and Sony A7 IV (BSI CMOS, 11.7 EV) edge ahead in pure dynamic range. The Nikon Z8 (Stacked CMOS, 11.3 EV) trails slightly. The R5 Mark II therefore sits in the upper mid-pack of its class without being the outright leader.

At high ISO the native range extends to 51 200 ISO, with an extension to 102 400 ISO. For wedding or indoor reportage shooters, noise remains usable up to 12 800 ISO according to DPReview visual tests, with gradual but controlled degradation beyond. The Canon EOS R3, with its 24.1 MP Stacked CMOS sensor, reaches higher native ISO (102 400 ISO native) thanks to lower pixel density, but it does not offer the resolution of the R5 Mark II.

Resolution and cropping: 45 MP in practice

45 MP on a 36 × 24 mm sensor yields a density of 6 720 × 4 480 pixels. In practice this allows aggressive cropping in post: a 50 % crop still leaves 22.5 MP usable, more than the native resolution of most mid-range full-frame mirrorless bodies. For large prints the resolution supports prints larger than 80 × 53 cm at 300 dpi without interpolation. This is a strong argument for portrait, landscape and reportage work where editorial cropping is common.

RAW is available in full-resolution uncompressed, lossless compressed and SRAW (reduced resolution). SRAW helps reduce buffer and storage pressure during long sequences. Canon also offers Custom Picture profiles directly in-camera, allowing fine JPEG tuning without Lightroom. This is appreciated by press photographers delivering straight from the field.

Human and animal eye detection: what works

Human and animal eye detection is enabled by default. In practice the system identifies and tracks a human face down to -6.5 EV, equivalent to a near-dark scene lit by a single candle at distance. This figure matches the Sony A7 IV (-4 EV) and exceeds the Panasonic Lumix S5 II (-6 EV). The Nikon Z8 claims -9 EV, but that value is measured under specific conditions that do not always reflect real-world moving-subject performance.

Animal detection covers dogs, cats, birds and some wildlife. Field tests published by DPReview confirm fast acquisition on birds in flight, a demanding use case that stresses both the stacked sensor’s readout speed and AF calculation precision. On this specific point the R5 Mark II rivals the Nikon Z8 and surpasses the Sony A7R V, whose conventional BSI sensor shows more pronounced rolling shutter in electronic burst.

Coverage and responsiveness in difficult conditions

100 % sensor coverage means the AF point can be placed right to the extreme edges of the frame. This is a direct advantage for off-centre compositions without cropping. The Canon EOS R3 offers the same coverage with the same 1 053 points, but on a 24.1 MP sensor: relative AF point density is therefore higher on the R3, which can matter on very small subjects in frame.

Overall AF responsiveness is boosted by the DIGIC X processor, which simultaneously handles stacked-sensor readout, AF calculation and buffer writing. At 30 fps electronic burst, tracking remains stable on subjects changing direction rapidly, according to independent tests consulted. It is the combination of stacked sensor plus fast processor that makes this possible: a conventional BSI sensor at 30 fps would produce unacceptable rolling shutter on fast lateral movement.

Electronic burst: 30 fps and real buffer

Electronic burst reaches 30 fps with AF tracking active. Mechanical burst is limited to 12 fps, which is standard for the class. The stated buffer is 93 RAW frames, roughly 3.1 seconds of continuous shooting at 30 fps before saturation. This figure should be interpreted with caution: Canon does not specify whether it was measured in uncompressed or compressed RAW. DPReview tests indicate the uncompressed RAW buffer is noticeably shorter. In lossless compressed RAW the 93 frames are achievable.

For comparison the Nikon Z8 reaches 120 fps electronic, four times faster. But the Z8 targets professional sports use that the R5 Mark II does not claim. At 30 fps the R5 Mark II comfortably covers wedding, reportage and general wildlife. The Canon EOS R3, with its 30 fps also, remains the choice for top-level sports in the Canon ecosystem thanks to its less demanding 24.1 MP sensor.

IBIS 8.5 stops: measurement conditions and real-world performance

IBIS is rated at 8.5 stops. This figure is measured to CIPA standards with a compatible stabilised lens. Without a stabilised lens, real-world performance typically drops to 5–6 stops according to independent tests, as noted by phototrend.fr. This is important: the 8.5 stops are not achievable with every RF lens.

I regularly shoot in demanding conditions, especially strong wind by the sea and low light at dusk. On these uses, effective 5-stop IBIS with a non-stabilised lens remains very useful for shutter speeds between 1/15 s and 1/60 s. The Nikon Zf claims 8 stops IBIS on a 710 g body, but its conventional CMOS sensor does not offer the same burst speed. The Panasonic Lumix S1R II also claims 8 stops IBIS for 3 200 USD, making it a serious rival on this specific criterion.

Codecs and bitrates: ProRes RAW in-camera

The R5 Mark II records in H.264, H.265, ProRes, ProRes RAW and Cinema RAW. Colour depth reaches 12-bit in RAW. Log is available natively. This codec list is exceptional for a mirrorless body: the Sony A7R V is limited to internal H.265 10-bit without ProRes. The Nikon Z8 offers internal 12-bit RAW but without ProRes. The R5 Mark II is the only body in its class to offer internal ProRes RAW without an external recorder.

Video tools include Waveform, False Color, custom LUTs and advanced white-balance management. These functions, usually reserved for cinema cameras, are directly accessible from the body menu. For a solo hybrid videographer this is a genuine time-saver on set.

8K/60p without overheating: what changed

Unlimited 8K recording is made possible by a complete thermal redesign. Canon does not disclose the technical details, but independent DPReview tests confirm the absence of thermal cut-off during extended 8K/30p and 4K/60p sessions. In 8K/60p some limitations may appear depending on ambient temperature, common to all bodies in this class.

8K resolution also allows comfortable cropping to 4K in post or extraction of 33 MP stills from video footage. This workflow is appreciated by wedding photographers covering decisive moments alone.

Video positioning versus the competition

The Panasonic Lumix S1R II offers 8K/120p for 3 200 USD, 1 100 USD less than the R5 Mark II. This is a strong argument for pure videographers. But the Lumix S1R II does not offer internal ProRes RAW and its AF is less reliable on subject detection according to Imaging Resource tests. The Canon EOS R5 C (4 499 USD) remains an alternative for videographers wanting a dedicated cinema body with the same 45 MP resolution, but it weighs 770 g and lacks IBIS.

For a video score of 9.1/10, the R5 Mark II earns its mark: no other full-frame mirrorless body combines internal ProRes RAW, unlimited 8K/60p and 8.5-stop IBIS in one chassis at this price.

The 630-shot CIPA rating is measured under standardised conditions that do not reflect real use. In practice a wedding photographer alternating bursts and posed shots can expect 400–500 shots per battery under normal conditions. The Nikon Z8 claims 340 CIPA shots, noticeably less. The Canon EOS R3 reaches 860 CIPA shots thanks to its larger LP-E19 battery. The R5 Mark II uses the LP-E6NH battery, compatible with existing Canon chargers, an advantage for already-equipped Canon users.

Wi-Fi and Bluetooth are standard. Wi-Fi supports direct FTP transfer to a remote server, appreciated by press photographers sending images from the field. USB-C 3.2 Gen 2 also enables high-speed wired transfer and body charging from an external power bank, extending runtime on long video shoots.

• 630 CIPA shots: above average for high-end full-frame mirrorless
• USB-C 3.2 Gen 2: fast transfer and body charging from external battery
• Full-size HDMI: external monitor connection without adapter
• Wi-Fi + Bluetooth: field FTP transfer and smartphone connection
• LP-E6NH battery: compatible with existing Canon battery ecosystem

Versus the Nikon Z8: speed versus versatility

The Nikon Z8 (45.7 MP, Stacked CMOS, 4 000 USD) is the most credible direct rival. It offers 120 fps electronic versus 30 fps for the R5 Mark II, making it the obvious choice for professional sports. But the Z8 weighs 910 g versus 746 g for the Canon, and its screen tilts but does not fully articulate. Dynamic range on the Z8 measures 11.3 EV versus 11.5 EV for the Canon. IBIS on the Z8 reaches 8 stops versus 8.5 stops for the Canon. On video the Z8 offers internal 12-bit RAW but without ProRes. The R5 Mark II is 299 USD more expensive yet lighter, better equipped for video and slightly superior in IBIS. Unless you shoot professional sports, the Canon is the better buy.

Versus the Sony A7R V: resolution versus speed

The Sony A7R V (61 MP, BSI CMOS, 3 900 USD) offers 16 MP more than the Canon, relevant for very large prints or extreme crops. But its conventional BSI sensor limits it to 10 fps electronic and produces more pronounced rolling shutter. Its dynamic range reaches 11.7 EV, slightly ahead of the Canon. IBIS is rated at 8 stops. The Sony A7R V is the best choice for static studio work at very high resolution. For any use involving movement the R5 Mark II is superior.

At launch the R5 Mark II costs 299 USD more than the Nikon Z8 and 399 USD more than the Sony A7R V. This premium is justified by the combination of internal ProRes RAW, 8.5-stop IBIS and fully articulated screen, none of which the Z8 or A7R V offer simultaneously. For a hybrid photo-video shooter the extra cost is rational.

On the used market the original Canon EOS R5 (45 MP, conventional CMOS, 20 fps) trades around 2 200–2 500 USD. For static photography without advanced video the original R5 remains a serious alternative at less than half the price of the Mark II. The main differences are electronic burst (20 fps versus 30 fps), rolling shutter (significantly reduced on the Mark II) and IBIS (8 stops claimed on the original versus 8.5 stops on the Mark II). If you do not need ProRes RAW video or 30 fps, the used original R5 is a rational purchase.

The R5 Mark II achieves what its direct rivals fail to do: combine 45 MP, 30 fps electronic, internal 8K ProRes RAW and 8.5 stops of IBIS in a 746 g weather-sealed body with dual card slots. No other full-frame body ticks all five boxes simultaneously at this price.

Its limitations are real but acceptable. Dynamic range of 11.5 EV is not the best in class. The 4 299 USD price is high. The RF ecosystem still lacks affordable long-reach lenses. And the 8.5 stops of IBIS require a stabilised RF lens to be reached.

• Buy it if you shoot both photo and professional video and refuse two bodies
• Buy it if wedding, high-resolution portrait or fast reportage is your core work
• Skip it if your use is exclusively static studio photography: the used original R5 at 2 300 USD is sufficient
• Skip it if you shoot professional high-speed sports: the Nikon Z8 at 120 fps is better suited
