Olympus's entry-level MFT with 20.3MP sensor, IBIS, and 4K video — compact and affordable.
The Olympus OM-D E-M10 Mark IV was released in 2020 as the compact entry-point MFT mirrorless, featuring a 20.3MP Live MOS sensor and 5-axis IBIS (4.5 stops) in the smallest OM-D form. 4K/30fps video. Built-in 2,360K-dot OLED EVF. BLS-50 battery. At approximately 383g with battery and card.
20.3MP Four Thirds Live MOS sensor. 4K/30fps; 1080/60fps. Built-in 2,360K-dot OLED EVF (1.23x magnification in Olympus convention, approximately 0.62x industry-standard equivalent). 5-axis IBIS rated 4.5 stops. BLS-50 battery. Approximately 383g with battery and card. Micro Four Thirds mount.
The 5-axis IBIS in the E-M10 IV body is rated at 4.5 stops — less than the E-M1 series (up to 7.5 stops via Sync IS) but significant for an entry-level mirrorless. The compact body and lightweight profile make the E-M10 IV the entry-point for the OM-D system, trading weather sealing and dual card slots for reduced size and price versus the E-M5 series.
On the used market the Olympus OM-D E-M10 Mark IV is affordable as a compact 20MP MFT mirrorless. Condition checks: BLS-50 battery health, EVF display quality, IBIS operation. No weather sealing. Compatible with all Micro Four Thirds lenses.
