Canon EOS R6 Mark IIvsSony a6700: Which to Buy
Both cameras shoot 4K with in-body stabilization, subject-detection autofocus and a fully articulated 3-inch screen. The deciding differences are sensor size and speed: the Canon pairs a full-frame sensor with much faster bursts, while the Sony is smaller, lighter and reaches higher frame rates in 4K.

Notes on 11 values — test conditions and caveats
- 1Canon EOS R6 Mark II, Native ISO maximum: ISO 204800 (H) is an expanded setting; the native range tops out at ISO 102400.
- 2Canon EOS R6 Mark II, In-body image stabilization: The 8-stop rating combines lens optical IS with in-body IS; results vary by lens.
- 3Canon EOS R6 Mark II, Pre-burst capture duration: Pre-release capture works in RAW burst mode and buffers up to 0.5s of action before full shutter press.
- 4Canon EOS R6 Mark II, Video codecs: Movies record H.264 by default; H.265/HEVC is used when Canon Log 3 or HDR PQ is enabled.
- 5Sony a6700, 4K max frame rate (full width): Full-width 4K tops out at 60p; 120p 4K uses a crop.
- 6Canon EOS R6 Mark II, Raw video recording: 6K ProRes RAW requires an external Atomos Ninja V+ recorder connected over HDMI.
- 7Canon EOS R6 Mark II, Video bit depth: Standard profiles record 8-bit 4:2:0; 10-bit 4:2:2 requires Canon Log 3 or HDR PQ.
- 8Canon EOS R6 Mark II, Battery life: 760 shots is the CIPA power-saving rating with the rear LCD; Canon's smooth-mode rating is 580 shots.
- 9Canon EOS R6 Mark II, Weather sealing: Sealed dust- and water-resistant build, not IP-rated; Canon cautions ingress cannot be fully prevented.
- 10Canon EOS R6 Mark II, USB charging & power delivery: In-body USB charging and power supply require Canon's optional PD-E1 USB power adapter.
- 11Canon EOS R6 Mark II, Minimum operating temperature: Canon's product manual rates 0–40°C; regional Canon spec sheets list a 2°C minimum.
Sensor size and low light
The Canon EOS R6 Mark II uses a 24.2MP full-frame sensor; the Sony a6700 uses a 26MP APS-C chip. The Canon's larger sensor gathers more light per pixel, so it holds up better indoors and at dusk, and its native ISO ceiling reaches 102,400 versus 32,000 on the Sony. That headroom means cleaner files in dim venues before you touch noise reduction.
The Sony still resolves slightly more pixels, which helps if you crop or print large in good light. The trade is low-light flexibility. Buyers who shoot events, weddings or night street scenes get more usable keepers from the Canon.
Speed and autofocus
The Canon is the faster stills camera: 12 fps with the mechanical shutter and 40 fps electronically, against 11 fps either way on the Sony. Its mechanical shutter also tops out at 1/8,000 s, double the Sony's, which matters when you want shallow depth of field in bright sun without an ND filter.
Subject detection differs by menu. The Canon recognizes humans, animals, birds, cars, trains, airplanes and motorcycles; the Sony swaps motorcycle for insect. Both track well. Sports and wildlife shooters gain the most from the Canon's burst rate and pre-burst buffer.
Video
Both record 4K at 10-bit and support log profiles, but they aim at different work. The Sony a6700 hits 120 fps in 4K, useful for slow-motion B-roll, though that mode uses a crop. Full-width 4K stops at 60p on both cameras, so the Canon gives you the same wide-field footage without cropping.
The Canon adds external raw: 6K ProRes RAW over HDMI to an Atomos Ninja V+. That is a real advantage for shooters who grade heavily, but it costs the price of the recorder. The Sony publishes 14 stops of dynamic range in log; the Canon does not publish a figure, so compare that claim against your own testing.
Handling, battery and size
The Canon is the bigger, heavier body at 670 g against 493 g, and it is larger in every dimension. That bulk buys a deeper grip, a higher-resolution viewfinder and a sharper rear screen, both of which make manual focus and framing easier.
The Sony's 122 mm width and 69 mm height make it an easy travel and street companion. Battery life splits the other way: the Canon is rated at 760 shots versus 570 on the Sony, helped by the power-saving LCD mode. The Canon also has two card slots and a dust- and drip-resistant build, so it suits working professionals who cannot stop for a card swap.
The Verdict
Buy the Canon EOS R6 Mark II if you shoot full-frame, need fast bursts, dual card slots and long battery life for paid or low-light work. Buy the Sony a6700 if you want a light APS-C body for travel and 4K120 slow motion, and can live with one card slot. Neither is a compromise pick — they solve different problems. Match the body to the jobs you actually shoot.

FAQ
Does the Canon R6 Mark II have a crop in 4K60?
No. Full-width 4K tops out at 60p on the Canon, and the Sony a6700 matches that at 60p full width. Only the Sony's 120 fps 4K mode applies a crop.
How much is the Canon EOS R6 Mark II?
It launched at $2,499. Sony has not published a launch price for the a6700.
Which camera has better image stabilization?
Canon rates the R6 Mark II at 8 stops, but that figure combines lens optical IS with in-body IS, so it depends on the lens attached. The a6700 is rated at 5 stops.
Is the Canon R6 Mark II weather sealed?
Canon describes it as dust and drip resistant, though it is not IP-rated and Canon cautions that ingress cannot be fully prevented. Sony has not published a comparable sealing rating for the a6700.
Can either camera record raw video?
The Canon can output 6K ProRes RAW, but only externally through an Atomos Ninja V+ over HDMI. The Sony a6700 has no raw video recording.
