Lens detail–Interchangeable Sony A-mount; compatible Sony, Minolta and Konica Minolta AF lenses. DT lenses trigger APS-C crop, but Sony does not guarantee full exposure performance with APS-C-only DT optics.
AutofocusFast Hybrid AF with up to 759 phase-detection points for stills or movies and approximately 94% still-image area coverage. Recognition covers people, animals, birds, insects, cars, trains and aircraft; Auto subject recognition supported. AF-S sensitivity is EV −6 to 20 with F1.2 at ISO 100, or EV −11 to 20 in the specified Bright Monitoring mode.TTL phase detection with nine selectable points (centre dual-cross) and ten non-selectable assist points; additional F2.8 precision sensor; single-shot, automatic and continuous AF, direct manual focus and manual focus; EV 0–18 detection at ISO 100; LED AF-assist lamp. AF micro-adjustment stores up to 30 lenses; no Eye-Start AF according to Sony’s exact Japanese table, despite the Hong Kong press table listing it.
ShutterMechanical and electronic shutters; exact Sony specifications list 30 seconds to 1/8000 second for stills, with Bulb for mechanical shooting. Flash sync 1/250 second full-frame or 1/320 second APS-C with compatible Sony flash; electronic first curtain supported.Electronically controlled vertical-traverse focal-plane shutter; 30 seconds to 1/8000 second plus Bulb; flash sync 1/250 second with stabilisation off or 1/200 second with it on; mirror-up drive mode
Burst detailUp to approximately 30 fps blackout-free electronic Hi+ with AF/AE tracking and up to 60 AF/AE calculations per second; mechanical Hi+ up to 10 fps. Maker buffer figures include 215 fine JPEG, 150 RAW or 65 compressed HQ RAW frames; card and recording conditions affect results. Pre-Capture and continuous-speed boost supported; lens compatibility affects maximum speed.Up to 5 fps Hi or 3 fps Lo; maker buffer claims 285 Standard JPEGs, 105 Fine JPEGs, 11 Extra Fine JPEGs, 12 RAW/cRAW or ten RAW/cRAW+JPEG frames; depends on memory card and shooting conditions
Stabilisation detailFive-axis sensor shift; Sony claims 8.5 stops at the centre and 7.0 at the periphery under CIPA 2024 pitch/yaw/roll conditions with FE 50mm F1.2 GM and long-exposure noise reduction off. Dynamic Active video stabilisation narrows the field of view more than Active mode.SteadyShot INSIDE sensor shift; Sony claims approximately 2.5–4 stops depending on lens and shooting conditions; excludes Minolta AF Macro Zoom 3X–1X F1.7–2.8
Flash–No built-in flash; proprietary Alpha flash shoe and PC sync terminal; ADI and pre-flash TTL with compatible external units. Wireless control requires an HVL-F58AM and another compatible flash.
Exposure controls–Program, aperture priority, shutter priority, manual and Auto; no scene modes; 40-segment honeycomb, centre-weighted or spot metering; ±3 EV compensation in 1/2- or 1/3-stop steps; D-Range Optimizer, 13 Creative Styles, Quick Navi and three saved shooting setups
Video
Highest video resolution7680 × 4320 at 30 fps–
Video detailXAVC HS 8K at approximately 30p/25p/24p supports 10-bit 4:2:2 or 4:2:0. 8K oversamples from 8.2K and narrows the field of view. Full-frame 4K 60p is uncropped; uncropped 4K 120p requires 4K angle-of-view priority On. Dual Gain Shooting works only at 4K 30p or lower. Sony's 120-minute 8K claim uses 30p 200 Mbps 4:2:0 10-bit, temperature setting High, monitor open and 25°C ambient; it is not an unconditional recording limit.Still-image DSLR without video recording or rear-screen live view; Intelligent Preview captures a temporary image for exposure, white balance and D-Range Optimizer simulation rather than a live feed
AudioBuilt-in stereo microphone and 3.5 mm microphone/headphone sockets. Optional XLR-A4 enables up to 96 kHz 32-bit float four-channel in-camera recording through the digital-audio Multi Interface Shoe; this is not an internal-microphone specification.–
