OM System OM-D E-M1 Mark II → OM System OM-1
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-1 is 2 generations newer to your OM System OM-D E-M1 Mark II, released 6 years later. Across the full spec sheet it improves 10 items and steps back on 2. The changes that matter most: burst jumps from 18fps to 50fps; 4K goes from 30p to 60p. The OM System OM-1 lists at $2,199 (the OM System OM-D E-M1 Mark II launched at $1,999, 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-1 if…
- ✓You shoot action, sports or wildlife — 50fps burst and 1,053 phase-detect points keeps up with fast, erratic movement where 18fps would drop frames.
- ✓You shoot video seriously — it brings smoother 60p 4K vs 30p.
- ✓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 -8 EV gives it the edge after dark.
Stick with the OM System OM-D E-M1 Mark II if…
- •None of the headline changes map to what you actually shoot — the camera you own doesn't get worse when a successor launches.
