Sony A6400 vs Sony A7 II
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
- Burst — mechanical: the A6400 leads at Continuous shooting: Hi+: 11 fps, Hi: 8 fps, Mid: 6 fps, Lo: 3 fps vs the A7 II's 5 fps (in High Continuous Shooting).
- EVF magnification: the A6400 leads at Approx. 1.07x (35mm camera equivalent: Approx. 0.70x) with 50mm lens at infinity vs the A7 II's Approx. 0.71 x (with 50mm lens at infinity, -1m).
- Weight (body): the A6400 leads at 403 g vs the A7 II's 599 g.

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.
