Olympus OM-D E-M10 Mark IV 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
- EVF resolution: the E-M10 IV leads at 2360K dots vs the OM-5's 2.360K dots.
- Burst — electronic: the OM-5 leads at Approx. 30fps (silent, H); Approx. 10fps (L) vs the E-M10 IV's Approx. 15fps.
- In-body stabilisation: the OM-5 leads at Up to 7.5 EV steps (Sync IS); Up to 6.5 EV steps (Sensor shift) vs the E-M10 IV's 4.5.

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.
