Sony A1 vs Sony A7 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 A1 leads at 9,437,184 dots vs the A7 IV's 3,686,400 dots (0.5-type Quad-VGA OLED).
- Resolution (MP): the A1 leads at 50.1 vs the A7 IV's 33.
- EVF magnification: the A1 leads at Approx. 0.90x (with 50-mm lens at infinity, -1 m-1) vs the A7 IV's Approx. 0.78x (with 50 mm lens at infinity, -1m-1).

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.
