OM System OM-3 vs Panasonic LUMIX GX9
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-3 if…
- ✓You shoot action, sports or wildlife — 25fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 9fps would drop frames.
- ✓You shoot video seriously — it brings smoother 60p 4K vs 30p, 10-bit internal colour, Log for gradable footage and both mic and headphone jacks for monitored audio.
- ✓You vlog or shoot handheld solo — the fully-articulating screen flips to face you and there's a mic input for clean audio.
- ✓You shoot in low light or indoors — AF that focuses down to -7.5 EV gives it the edge after dark.
