Maximum continuous burst40 fps30 fps
AutofocusPhase Hybrid AF using phase and contrast detection; human, animal, car, motorcycle/bicycle, train and aircraft recognition; −6 to 18 EV with f/1.4 lens, ISO 100 and AFS. Subject type must be selected manually (both reviews)Phase Hybrid AF combines phase and contrast detection; 779-area system (maker UK). Current Japan table recognises people, animals, cars, motorcycles, trains and aircraft; launch reviews described only people/animals, so later recognition is not treated as a launch feature. Continuous autofocus while zooming requires compatible lens firmware
ShutterMechanical 60–1/8000 second and Bulb to approximately 30 minutes; electronic first curtain 60–1/2000; electronic image-priority 60–1/8000 or speed-priority 60–1/16000, 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 SH 40 or 20 fps with AFS/AFC/MF; SH buffer 70 RAW/JPEG or 65 HEIF frames. Mechanical speed-priority H+ up to 10 fps AFC, or 8 fps AFC with live view; image-priority H+ 9 fps AFC, or 7 fps AFC with live view. Current maker settings supersede older review reports that electronic 20 fps was unavailableFull-resolution electronic SH30 at 30 fps AFS/AFC/MF; SH buffer 200 RAW/RAW+JPEG/JPEG frames in the current maker table. Mechanical/electronic-first-curtain 9 fps AFS/MF or 7 fps AFC; normal electronic 9/8 fps respectively. Normal RAW/RAW+JPEG at least 200 and JPEG at least 300 frames under maker conditions. UK launch article's broad 300-frame statement is not substituted for the current SH limit
Stabilisation detailFive-axis sensor-shift B.I.S., eight centre/seven corner stops with S-R2060 at 60 mm; Dual I.S.2 seven centre/corner stops with S-R24105 at 105 mm, CIPA-2024. Electronic video IS is separate; current Japan table marks crop-less mode as firmware 3.0Five-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 (Panasonic Australia). Active I.S. provides additional video correction, with mode 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

Video detailCurrent maker supplement lists internal 8064×5376 3:2 open-gate HEVC 4:2:0 10-bit at 23.98/24p; 8128×4288 17:9 at 29.97p and 7680×4320 UHD at 29.97p. Internal 5760×3040 ProRes RAW HQ/RAW up to 29.97p; image-area and media restrictions depend on mode. HDMI RAW 8128×5418 at 23.98p is external-recorder output, not the internal headline. Open-gate 8.1K was a promised firmware upgrade at launch and appears in the current maker table; no launch availability inferredInternal 5952×3968 3:2 open-gate 6K at 29.97p, 4:2:0 10-bit HEVC 200 Mbps; 5952×3136 17:9 at 29.97p also supported. C4K/4K up to 59.94p uses APS-C crop; lower frame rates have full-frame modes. Full HD high-speed modes have separate sensor-output/crop limits. Built-in cooling fan; maker UK specifies 0–40 °C for its unlimited-recording claim, while 6K/5.9K stops once after 30 minutes with Thermal Management STANDARD. No S5IIX internal ProRes, SSD or streaming features copied
