OM System OM-1 Mark II vs Panasonic LUMIX GH5S
The bottom line
These two are closely matched. The differences below are where they diverge — weigh the ones that map to how you actually shoot, and let price and handling break the tie.
Choose the OM System OM-1 Mark II if…
- ✓You shoot action, sports or wildlife — 50fps burst and 1,053 phase-detect points keeps up with fast, erratic movement where 12fps would drop frames.
- ✓You want maximum detail for landscapes, studio or large prints — 20.4MP resolves noticeably more than 10.2MP and gives more cropping latitude.
- ✓You shoot handheld — in-body stabilisation lets you use slower shutter speeds and steadies video, which the other body can't do without a stabilised lens.
- ✓You shoot in low light or indoors — AF that focuses down to -9 EV gives it the edge after dark.
Choose the Panasonic LUMIX GH5S if…
- ✓You shoot in low light or indoors — a higher native ISO ceiling (51,200) gives it the edge after dark.
