Sony A7 II vs Sony A7R III
Every spec below is quoted from the makers' official pages — where a figure isn't published we say so rather than guess. Sizes are drawn at true relative scale from published dimensions, and the bag-fit row is computed against our measured bag catalog.
The 3 biggest published differences
- EVF resolution: the A7R III leads at 3,686,400 dots vs the A7 II's 2 359 296 dots (0.5"-type electronic viewfinder (color)).
- Burst — mechanical: the A7R III leads at 10 vs the A7 II's 5 fps (in High Continuous Shooting).
- Resolution (MP): the A7R III leads at 42.4 vs the A7 II's 24.3.
