Sony A7 II vs Sony A7R IV
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 IV leads at 5,760,000 dots (1.3 cm (0.5 type) electronic viewfinder, UXGA OLED) vs the A7 II's 2 359 296 dots (0.5"-type electronic viewfinder (color)).
- Resolution (MP): the A7R IV leads at 61.0 vs the A7 II's 24.3.
- Burst — mechanical: the A7R IV leads at Continuous shooting: Hi+: max. 10 fps, Hi: max. 8 fps, Mid: max. 6 fps, Lo: max. 3 fps vs the A7 II's 5 fps (in High Continuous Shooting).

Spec values are the manufacturers' published figures, compared factually — we don't rank cameras. Fit verdicts are planning estimates from published interior dimensions, not guarantees. See methodology.
