OM System OM-D E-M10 Mark III vs OM System OM-D E-M10 Mark IV
The bottom line
Same line, different generation: the OM System OM-D E-M10 Mark IV (2020) moves ahead on burst speed (15fps vs 8fps), resolution (20.3MP vs 16.1MP) and in-body stabilisation. The OM System OM-D E-M10 Mark III is still the value pick at $699 ($799 for the OM System OM-D E-M10 Mark IV). If those newer features aren't ones you'll actually use, the OM System OM-D E-M10 Mark III gives you most of the experience for less.
Choose the OM System OM-D E-M10 Mark IV if…
- ✓You shoot action, sports or wildlife — 15fps burst and 121 phase-detect points keeps up with fast, erratic movement where 8fps would drop frames.
- ✓You shoot video seriously — it brings 10-bit internal colour.
