- Video: 4K60 (Super 35 crop), 4K30 full-width 7K oversampled
Canon EOS R6 Mark II
Speed-first full-frame body with superb autofocus.
- Sensor: 24.2MP full-frame CMOS
- Video: 4K60 uncropped, oversampled from 6K
Our recommendation
Buy the Sony A7 IV if you shoot mixed stills and video and want maximum versatility; buy the Canon EOS R6 Mark II if your subjects move fast and keeper rate on action is the priority. Resolution favors Sony, speed favors Canon, and there is no wrong answer, only a wrong match to your shooting.
Resolution vs speed
The A7 IV's 33MP sensor gives roughly 35 percent more pixels than the R6 II's 24.2MP, which shows in cropping latitude and large prints. The R6 II answers with 40 fps electronic bursts against the Sony's 10 fps: for a bird in flight sequence, Canon captures four times the decisive-moment options.
Autofocus behavior
Both offer excellent subject detection, but Canon's implementation tracks erratic subjects slightly more tenaciously, while Sony's wider lens-assisted ecosystem (more fast telephotos from Sigma and Tamron) can matter more than the body difference for wildlife reach on a budget.
Video and stabilization
The R6 II records uncropped 4K60 oversampled from 6K; the A7 IV crops to Super 35 at 4K60 but offers 10-bit 4:2:2 in both. Canon's 8-stop IBIS beats Sony's 5.5 stops for handheld video and long-lens stills. Hybrid shooters splitting evenly should weigh the crop against the stabilization.
Choose Sony A7 IV if…
- You crop heavily or print large and want 33MP of headroom
- You want the deepest native and third-party lens catalog
- Your work splits evenly between stills and video
Choose Canon EOS R6 Mark II if…
- You shoot sports, wildlife, or events where burst rate decides keepers
- You handhold long lenses and want 8-stop stabilization
- You want the cleanest uncropped 4K60 footage
Questions, answered
Which has better low-light performance?
The R6 II has a small edge: its 24.2MP sensor's larger photosites produce slightly cleaner high-ISO files. In practice both are excellent to ISO 6400, and lens aperture matters more than the body difference.
Can Canon match Sony's lens selection?
Not in breadth. Sony E-mount's third-party autofocus support from Sigma, Tamron, and others has no equal. Canon RF first-party glass is superb, but expect fewer budget alternatives.
Which is better for weddings?
The A7 IV, narrowly: 33MP gives cropping flexibility for ceremony candids, dual card slots cover redundancy, and the lens catalog offers affordable fast primes. The R6 II's speed matters less when subjects pose.
