Autofocus121-point contrast detection with single, nine-point group or all-area selection; face and near-eye detection, continuous tracking and manual-focus peakingContrast AF, face/eye detection, tracking and 49-area selection; AFS/AFF/AFC/MF modes
ShutterMechanical 1/4000–60 seconds; electronic 1/16000–60 seconds; electronic first curtain 1/320–60 seconds, switching to mechanical first curtain at faster speeds; Bulb, Live Time and Live CompositeElectronic front curtain up to 1/500 second; electronic shutter up to 1/16000 second. Flash synchronisation 1/50 second or slower
Burst detailElectronic high approximately 15 fps with focus fixed at the first frame, reported by Amateur Photographer; electronic low 6.3 fps. Mechanical high 8.7 fps and low 5 fps; continuous autofocus requires the low-speed setting. Maker electronic-high buffer 42 RAW or 49 large-fine JPEG with specified KIOXIA UHS-II cardNative electronic 10 fps; electronic first curtain 6 fps AFS/MF or 5 fps AFF/AFC. Maker RAW buffer at least 20 frames under its test conditions; video-derived 4K Photo is separate
Stabilisation detailFive-axis sensor shift, rated up to 4.5 CIPA stops with M.Zuiko Digital ED 14–42mm F3.5–5.6 EZ at 42 mm; movie M-IS1 adds electronic correction with a field-of-view crop, M-IS2 uses sensor stabilisation aloneOptical stabilisation depends on the attached lens; no sensor-shift Body I.S. Video electronic stabilisation combines with compatible optical lenses, marketed as 5-axis Hybrid I.S. rather than lens-plus-sensor stabilisation; 4K correction and crop differ. High electronic setting narrows the view further
FlashBuilt-in flash, guide number 7.6 at ISO 200; hot shoe; mechanical flash synchronisation up to 1/250 secondBuilt-in TTL pop-up flash; maker guide number 5.1 at ISO 200 or 3.6 at ISO 100
