OM System OM-1 Mark II vs Panasonic Lumix G9 II
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 G9 II leads at Approx. 3.68 million dots vs the OM-1 II's Approx. 5.76M dots.
- Burst — electronic: the G9 II leads at SH75: 75 frames/sec (AFS/MF); SH60: 60 frames/sec (AFS/AFC/MF); H: 14 frames/sec (AFS/MF), 9 frames/sec (AFC) vs the OM-1 II's Pro Capture SH1 approx. 120fps; SH2 approx. 50fps (213-frame RAW buffer at 120fps).
- In-body stabilisation: the OM-1 II leads at Up to 8.5 EV steps (Sync IS) vs the G9 II's B.I.S. (5-axis / 8.0-stop); Dual I.S. 2 (7.5-stop) (CIPA standard).
