OM System OM-5 vs Sony A6400
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 magnification: the OM-5 leads at Max. 1.37x with a 50mm lens vs the A6400's Approx. 1.07x (35mm camera equivalent: Approx. 0.70x) with 50mm lens at infinity.
- Resolution (MP): the A6400 leads at 24.2 vs the OM-5's 20.4 Megapixels (effective); 21.8 Megapixels (full).
- EVF resolution: the OM-5 leads at 2.360K dots vs the A6400's 2 359 296 dots.

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.
