OM System OM-D E-M10 Mark IV vs OM System PEN
The bottom line
Same line, different generation: the OM System PEN (2026) moves ahead on burst speed (30fps vs 15fps) and subject-detection AF. The OM System OM-D E-M10 Mark IV is still the value pick at $799 ($999 for the OM System PEN). 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-D E-M10 Mark IV if…
- ✓You shoot video seriously — it brings 10-bit internal colour.
- ✓You're budget-conscious — it launched at $799, about $200 less, freeing money for lenses.
Choose the OM System PEN if…
- ✓You shoot action, sports or wildlife — 30fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 15fps would drop frames.
- ✓You shoot video seriously — it brings Log for gradable footage.
- ✓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 -3.5 EV gives it the edge after dark.
