Stabilisation detail	Five-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 3.0	Five-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
Flash
Flash	External flash support, no built-in flash (Photography Blog); sync up to 1/250 second with maker flash-output restrictions	No built-in flash and no external-flash support; accessory shoe is a cold shoe

Maker video table lists internal ProRes RAW HQ/RAW 5760×3040 up to 29.97p and C4K up to 59.94p; HDMI RAW 6000×4000 up to 29.97p needs an external recorder and is not the headline internal resolution. ARRI LogC3 requires separately purchased DMW-SFU3A key; recording formats, media and firmware impose restrictions	Internal 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)
