Lens detailL-Mount full-frame lenses; APS-C lenses use a reduced image area, with 3984×2656 3:2 stills–
AutofocusPhase Hybrid AF with up to 779 phase-detection and 315 contrast positions; humans/animals/cars/motorcycles and bicycles/trains/aircraft; −6 to 18 EV with f/1.4 lens, ISO 100, AFS. Subject selection is manual; current maker table includes Urban Sports recognitionPhase Hybrid AF combines phase and contrast detection; 779 points (maker US). Current Japan recognition includes people, animals, cars, motorcycles, trains and aircraft; launch-era reviews described fewer subjects, so later firmware recognition is not treated as a launch feature. Continuous autofocus during zooming requires compatible updated lens firmware
ShutterMechanical 60–1/8000 second and Bulb to approximately 30 minutes; electronic first curtain 60–1/2000; electronic 60–1/16000 with Bulb to approximately 60 secondsMechanical 60–1/8000 second, Bulb approximately 30 minutes; electronic first curtain 60–1/2000 with the same Bulb maximum; electronic 60–1/8000 with Bulb approximately 60 seconds
Burst detailFull-resolution electronic 70 fps speed-priority or 60/30 fps image-priority with AFS/AFC/MF; SH buffer 180 JPEG/RAW or 170 HEIF frames under maker conditions. Mechanical speed-priority up to 10 fps, including H+ AFC; lower modes offer live view. No composite high-resolution output counted as sensor resolutionFull-resolution electronic SH30 at 30 fps AFS/AFC/MF; SH30 PRE added in version 2.0. Current SH buffer 200 RAW/RAW+JPEG/JPEG frames. Mechanical/electronic-first-curtain 9 fps AFS/MF or 7 fps AFC; normal electronic 9/8 respectively. Normal RAW/RAW+JPEG buffer at least 200 and JPEG at least 300 frames under maker media/test conditions
Stabilisation detailFive-axis sensor-shift B.I.S., eight centre/seven corner stops with S-R2060 at 60 mm; compatible Dual I.S.2 gives seven centre/corner stops with S-R24105 at 105 mm under CIPA-2024. Electronic video IS separately available; current Japan table marks crop-less mode as firmware 3.0Five-axis sensor-shift B.I.S. with compatible-lens Dual I.S.2; maker US Dual I.S.2 claim 6.5 stops under CIPA yaw/pitch conditions with S-E70200 at 200 mm and updated lens firmware. Active I.S. optimises video correction; electronic video modes have separate restrictions
FlashExternal flash support, no built-in flash (Photography Blog); sync up to 1/250 second with maker flash-output restrictionsNo built-in flash; external flash sync up to 1/250 second, with reduced guide number and maker restrictions at the fastest sync setting
Exposure controlsSeparate still/video/S&Q controls and custom settings; V-Log maker claim 14+ stops, or 15 with Dynamic Range Boost; no measured stills dynamic range inferred–
