Olympus OM-D E-M10 Mark IV 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 E-M10 IV's 2360K 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 E-M10 IV's Approx. 15fps.
- Weight (body): the E-M10 IV leads at 383 g vs the G9 II's 658 g.
