Maximum continuous burst9 fps9 fps
AutofocusContrast AF with DFD, human/animal detection, tracking and 225-area selection; firmware adds head recognition and tracking improvementsPhase/contrast hybrid TTL AF; AFS/AFC/MF, tracking/full-area/zones/single-area/pinpoint. Current Japan recognition includes people, animals, cars, motorcycles, trains and aircraft; maker firmware version 1.1 added trains/aircraft and additional vehicle target parts, rather than assumed launch support
ShutterMechanical, electronic front curtain and electronic modes; maker rated shutter life approximately 400000 imagesElectronic shutter only; stills 60–1/8000 second, with maximum exposure shorter above ISO 1600. Time mode approximately 60 seconds; Bluetooth remote permits Bulb under maker restrictions
Burst detailNative 9 fps AFS/MF; mechanical/electronic front curtain 6 fps AFC or electronic 5 fps AFC. Maker buffer more than 90 RAW, 70 RAW+JPEG or 999 JPEG with Sony XQD G-series card. Reduced-resolution video-derived 6K/4K Photo modes are separateNormal full-resolution electronic H burst 9 fps AFS/MF or 8 fps AFC; at least 55 RAW, 35 RAW+JPEG or 120 JPEG frames under maker test/media conditions. SH/SH PRE is a separate 30 fps AFS/AFC/MF burst limited to 36 frames (approximately 1.2 seconds), excluded from the headline continuous-burst figure; medium/low-speed modes have different buffers
Stabilisation detailFive-axis Body I.S.; firmware 1.2 dated 9 July 2019 raises maker rating from 5.5 to 6 stops with S-X50 at 50 mm. Compatible-lens Dual I.S. 2 rises from 6 to 6.5 stops with S-R24105 at 105 mm or S-R70200 at 200 mm, CIPA yaw/pitchFive-axis sensor-shift B.I.S. rated five stops with S-R2060 at 60 mm; compatible-lens Dual I.S.2 rated 6.5 stops with S-E70200 at 200 mm, CIPA yaw/pitch conditions. Electronic video stabilisation and Boost I.S. are separate modes, not the basis of the Dual I.S.2 stills rating

Video
Highest video resolution3840 × 2160 at 60 fps5952 × 3968 at 29.97 fps
Video detailOptional 5952×3968 6K at maker-labelled 24p requires optional DMW-SFU2 software-key activation and firmware 2.0 dated 6 April 2021; 4:2:0 10-bit LongGOP 200 Mbps. The upgrade also enables 5.9K30/25/24p, 5.4K30/25p, C4K modes and external 12-bit RAW with compatible recorder. Standard launch body offers UHD 3840×2160 up to 60p in 8-bit; 4K60 uses crop and a 30-minute clip limit. Higher-quality internal 10-bit, V-Log and associated advanced modes require the appropriate software-key upgrade; not included in the standard body configurationInternal 5952×3968 3:2 open-gate 6K at 29.97p, 4:2:0 10-bit HEVC Long GOP 200 Mbps; 5952×3136 17:9 also available. C4K/4K at 59.94p uses APS-C crop; Full HD high-speed modes have separate crop/frame-rate restrictions. Firmware 1.1 (9 October 2024) added a recording-limit menu and an option without the timer; internal temperature can still stop recording. Launch reviews' 10-minute 6K/15-minute 4K timer limits are historical, not the sole current setting. No cooling fan (TechRadar)

Advanced recording firmware and optional-key requirements are separate from original release specifications. No inferred direct successor across co-sold S1/S5 generationsGerman maker confirms June 2024 availability; Japanese maker gives 20 June for its market. Month retained globally rather than treating the Japanese day as verified UK first sale
