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 recognitionFast Hybrid AF with up to 759 phase-detection points; recognition for humans, animals, birds, insects, cars, trains and aeroplanes, plus automatic subject selection. Maker claims up to 94% frame coverage; AF-S detection down to EV −4 with an F2.0 lens at ISO 100.
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 secondsElectronic shutter 1/16000 second to 30 seconds; mechanical shutter 1/8000 second to 30 seconds plus Bulb; full-frame flash sync 1/250 second
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 resolutionHi+ up to 30 fps electronically with AF/AE tracking and 14-bit RAW, or 10 fps mechanically. Electronic Hi+ is blackout-free; speed depends on lens, card, format and shooting conditions. Pre-capture can retain up to one second before full shutter press. Maker maximum-speed buffer figures include 185 Fine JPEG, 95 RAW or 35 lossless-compressed RAW photographs under its 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; maker claims 7.5 stops at the centre and 6.5 at the periphery under CIPA 2024 pitch/yaw/roll conditions with FE 50mm F1.2 GM and long-exposure noise reduction off. Dynamic Active movie mode adds more crop than Active mode.
FlashExternal flash support, no built-in flash (Photography Blog); sync up to 1/250 second with maker flash-output restrictions–
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–
