OM System OM-1 vs Panasonic Lumix GH6
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 GH6 leads at OLED Live View Finder, approx. 3.68 million dots vs the OM-1's 5760K dots.
- Burst — mechanical: the OM-1 leads at 50fps C-AF & AE Tracking (RAW) vs the GH6's 14 frames/sec (AFS/MF), 8 frames/sec (AFC).
- Burst — electronic: the OM-1 leads at 120fps S-AF (RAW) vs the GH6's SH75: 75 frames/sec (AFS/MF).

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.
