Fujifilm X-Pro3 vs OM System OM-5
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
- Resolution (MP): the X-Pro3 leads at 26.1 millions pixels vs the OM-5's 20.4 Megapixels (effective); 21.8 Megapixels (full).
- EVF resolution: the X-Pro3 leads at Hybrid viewfinder: OVF (reverse Galilean with electronic bright frame display, coverage approx. 95%) + EVF 0.5 inch approx. 3.69 millions dots OLED Color Viewfinder (4:3) vs the OM-5's 2.360K dots.
- EVF magnification: the OM-5 leads at Max. 1.37x with a 50mm lens vs the X-Pro3's EVF 0.66x with 50mm lens (35mm equivalent) at infinity and diopter set to -1m-1; OVF approx. x0.52.

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.
