Approximate values measured with a KIOXIA 64 GB UHS-II card.

OM SYSTEM		—
USB charging and powerThe battery charges in the camera over USB-C; USB PD can power the camera externally

Powering needs a USB PD source rated at 27 W or more (9 V 3 A, 15 V 2 A or 15 V 3 A).

Processor and AI—BIONZ XR image processor and dedicated AI processing unit

The AI unit uses human body and pose data for subject recognition; Sony says vehicles and insects are now recognised as well as people.

Sony
Image stabilisation—5-axis sensor-shift stabilisation; 8.0 stops per CIPA (with FE 50 mm F1.2 GM, pitch/yaw only)

The 8-stop figure applies to a specific lens and test condition; the effect varies with other lenses. Active mode in video adds stabilisation but crops the image.

Sony
Shutter and burst—1/8000–30 s and Bulb; mechanical and electronic shutter; 10 fps in Hi+ mode

Exposures longer than 30 seconds need Bulb mode or an external intervalometer.

Sony
Monitor—3.2-inch TFT, 2,095,104 dots; fully articulating (up 98°, down 40°, side 180°, rotation 270°)

The screen both flips out to the side and tilts on the horizontal axis; this four-way design helps with vertical shots and gimbal work.

Sony
Video—8K 24p (25p) and 4K 60p (50p); XAVC S (H.264) and XAVC HS (H.265)

H.265 (XAVC HS) gives smaller files at the same quality but needs a more powerful computer to edit.

Sony
Pixel Shift—Pixel Shift Multi Shooting: 4 or 16 shots

The sensor is shifted by a pixel between frames; frames combined on a computer give higher colour resolution or a bigger image. It needs static subjects and a tripod.

Sony
Card slots—Two slots; each takes SD (UHS-I/UHS-II) or CFexpress Type A

CFexpress Type A clears the buffer faster in 8K and long bursts; SD cards also work.

Sony
Connectivity—USB-C (10 Gbit/s, USB 3.2), power and charging via USB Power Delivery; Wi-Fi 802.11ac (2.4/5 GHz); Bluetooth 5.0

USB PD lets the camera run from a power bank or adapter while shooting; 10 Gbit/s suits file transfer and streaming.

Sony
