OM System OM-D E-M10 Mark III → OM System OM-D E-M10 Mark IV
Is the upgrade worth it? Every change on the spec sheet, and an honest read on who should bother.
The bottom line
The OM System OM-D E-M10 Mark IV is the direct successor to your OM System OM-D E-M10 Mark III, released 3 years later. Across the full spec sheet it improves 10 items and steps back on 1. The changes that matter most: burst jumps from 8fps to 15fps; resolution rises from 16.1MP to 20.3MP; in-body stabilisation is added. The OM System OM-D E-M10 Mark IV lists at $799 (the OM System OM-D E-M10 Mark III launched at $699, and older bodies typically sell for well under launch price on the used market). If several of the gains below map to how you shoot, this is a substantial step up; if none do, your current body keeps doing everything it does today.
Upgrade to 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.
- ✓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.
Stick with the OM System OM-D E-M10 Mark III if…
- •None of the headline changes map to what you actually shoot — the camera you own doesn't get worse when a successor launches.
