Canon EOS R5 Mark IIvsNikon Z9: Which to Buy?

Resolution is effectively a tie: 45 megapixels on the Canon EOS R5 Mark II against 45.7 on the Nikon Z9, a difference no one will see in a print. Both use stacked full-frame sensors, so readout is quick and rolling-shutter distortion is kept down in electronic mode. Neither maker publishes a readout figure, and neither publishes a log dynamic-range rating, so there is nothing to separate them on paper there either.

Handheld shooting is where the Canon pulls ahead. Its in-body stabilization is rated at 8.5 stops, and the Nikon's 6-stop figure only applies with Synchro VR, meaning a compatible lens that adds its own 2-axis VR on top of the body's 5-axis system. If you shoot long lenses or slow shutter speeds without a tripod, the Canon gives you more margin on every frame.

The Canon shoots electronic bursts at 30 fps, the Nikon at 20 fps. If you photograph birds, sprinting athletes or any fast, unpredictable action, that extra third of a second of coverage per second is real: more frames of the peak moment, and more chances one of them is sharp. The Nikon's mechanical-shutter figure is not published because the Z9 has no mechanical shutter at all, so its 20 fps electronic number is the only one that applies.

Pre-burst favors the Nikon. It buffers a full second before you press the shutter, against roughly half a second on the Canon, and that only works in the Z9's C30 and C120 capture modes. Pre-burst is a timing tool: the longer window means fewer missed launches, jumps and reactions. The Canon's edge is the slower mechanical shutter ceiling versus the Nikon's 1/32,000 s, which only matters in bright light at wide apertures.

Both record 8K internally and both do raw internally, which is the headline. The practical split is frame rate at full sensor width. The Canon manages 4K at 59.94 fps across the full width of the sensor, while the Nikon drops to 30 fps at full width and reaches 120 fps in 4K only by cropping or subsampling in the mode that provides it. For anyone shooting 4K for slow-motion or for a 60p deliverable, the Canon is the simpler camera to work with.

The Nikon counters with ProRes 422 HQ and N-RAW alongside H.264, HEVC and ProRes RAW, so if your post pipeline is built around ProRes or Nikon's raw format, the Z9 fits without a transcode step. Canon's internal codecs are XF-HEVC S, XF-AVC S and H.264 MP4, with ProRes RAW routed out over HDMI to an external recorder. Both are 10-bit and both offer log profiles.

The Canon's viewfinder is noticeably denser at 5.76 M dots against 3.69 M dots, which makes manual focusing and checking fine detail easier before you shoot. The Nikon's finder is slightly larger at 0.8x against 0.76x, a comfort difference rather than a detail one. Rear screens match on resolution, but the Canon's is fully articulated and the Nikon's tilts, and that is a genuine workflow choice: the Canon flips to face you for vlogging and low-angle verticals, the Nikon is quicker to pull out for waist-level stills.

Size and weight are the other everyday factor. The Canon is 746 g and clearly smaller in width and height, so it is the one you carry all day without noticing. The Nikon is 1,340 g and 149 mm tall, a body that balances long glass but punishes a light bag. Both are dust and drip resistant, both have two card slots, both charge and power over USB, and both give you a full-size HDMI port.

The Nikon is rated for 740 shots against the Canon's 630, roughly one extra card's worth of shooting before a swap. On a long event day that is the difference between changing a battery and not. Neither figure accounts for video, where both drain far faster than the stills rating suggests.

The Nikon also keeps working down to -10 °C, while the Canon is rated only to 0 °C. If you shoot winter sports, night skies or anything else in genuine cold, the Nikon is the body rated to keep going when the temperature drops below freezing.
