Canon EOS R5 Mark IIvsSony RX100 VII: Full-FramevsPocket

The Canon EOS R5 Mark II uses a 45 MP full-frame sensor; the Sony RX100 VII uses a 20.1 MP 1-inch sensor. That gap decides low-light shooting and cropping headroom. A full-frame sensor gathers more total light at the same aperture, so the Canon keeps dynamic range and detail in dim rooms where the Sony starts to show noise. The 45 MP count also leaves room to crop a bird or athlete tight and still print large.

The Sony is not built for that kind of pushing. Its 1-inch sensor is a fraction of the area, and its 12,800 ISO ceiling suits daylight and well-lit interiors. In-body stabilization is a second gap: the Canon is rated 8.5 stops versus 4 stops for the Sony, and the Sony figure reflects lens-shift SteadyShot at the telephoto end rather than a body-only rating. Handheld the Canon holds a slower shutter speed.

The Canon recognizes humans, animals, birds, cars, trains, airplanes, and motorcycles. The Sony recognizes only humans and animals. For anyone shooting wildlife or motorsport, that difference means the Canon can acquire and hold a subject the Sony will not identify at all, leaving you to track manually.

Burst rates favor the Canon too, and both cameras are fast. The R5 Mark II does 12 fps with the mechanical shutter and 30 fps electronically. The Sony hits 20 fps blackout-free with AF tracking, and a separate Single Burst mode fires 7 shots at up to 90 fps, but its 10 fps mechanical rate is the ceiling when you want a real shutter. The Canon also buffers up to 15 frames before you press the shutter fully, roughly half a second of pre-capture, which Sony does not publish.

The Canon shoots 8K and does 4K at 59.94 fps full width. The Sony tops out at 4K 30 fps and records H.264 only. If you deliver 4K/60 or want to reframe 8K footage in post, the Sony cannot do the job at all, and its lack of HEVC is a real limitation for anyone archiving high-bitrate footage.

Raw video is the sharper split. The R5 Mark II records Cinema RAW Light internally and ProRes RAW externally over HDMI, with 10-bit depth. The Sony offers no raw video in any form. The Sony does support S-Log2, S-Log3, and HLG through Picture Profiles, so it is not a slouch for grading, but colorists working in raw will need the Canon. The Canon's full-size HDMI also connects to a monitor or recorder without an adapter.

The Canon's viewfinder is 5.76 M dots at 0.76x; the Sony's is 2.36 M dots at 0.59x. For manual focus or checking critical sharpness, the Canon is in a different class, and its rear screen is 2.1 M dots against 0.92 M dots on the Sony. The Canon screen is fully articulated, so it flips out for vlogging or low angles. The Sony only tilts.

Battery life is the other gap that matters on a shoot day. The Canon is rated 630 shots; the Sony is rated 260, or 310 with the Auto Monitor Off setting at 2 seconds. Two card slots on the Canon give you backup or separate stills and video cards, while Sony does not publish slot count. What the Sony offers instead is size: it weighs 302 g against 746 g and packs into a jacket pocket, where the Canon needs a bag.

The Canon is the clear answer for sports and wildlife. Its AF subject categories include birds, cars, trains, airplanes, and motorcycles, none of which the Sony claims to detect. Combined with 30 fps electronic shooting, 0.5 seconds of pre-capture, and 8.5 stops of stabilization for long lenses, the R5 Mark II is built for fast, unpredictable subjects.

The Sony has a lens advantage in reach, since its fixed zoom covers 24–200 mm equivalent in a body that fits a pocket, and 20 fps with tracking is genuinely fast. But without bird or vehicle recognition, and capped at 4 stops of stabilization at 200 mm, the shooter ends up doing more of the work. Buy the Sony for casual reach, not for a sidelines or safari kit.
