OM System OM-D E-M10 Mark IV vs OM System OM-3
The bottom line
Same line, different generation: the OM System OM-3 (2024) moves ahead on burst speed (25fps vs 15fps), 4K frame rate (60p vs 30p) and subject-detection AF. The OM System OM-D E-M10 Mark IV is still the value pick at $799 ($899 for the OM System OM-3). If those newer features aren't ones you'll actually use, the OM System OM-D E-M10 Mark IV gives you most of the experience for less.
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 15fps would drop frames.
- ✓You shoot video seriously — it brings smoother 60p 4K vs 30p, 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.
Where they differ
- ›Video: the OM System OM-3 is the stronger video tool — 4K up to 60p, 10-bit internal and Log.
- ›Price: the OM System OM-D E-M10 Mark IV launched at $799, $100 under the OM System OM-3 — money that could go toward glass.
- ›Burst: the OM System OM-3 shoots 25fps to the OM System OM-D E-M10 Mark IV's 15fps — the gap that decides whether you nail the peak moment in sports and wildlife.
- ›Durability: the OM System OM-3 is weather-sealed against dust and rain; the other isn't.
