SensorAPS-C (23.3 × 15.5 mm) Exmor R CMOS; approx. 26.0 MP effective (27.0 MP total)

Exmor R is a back-illuminated sensor: the circuitry sits behind the light-gathering surface, so more light reaches the pixels. Video uses up to about 19.9 MP of the sensor.

Sony		35 mm full-frame (35.9 × 23.9 mm) back-illuminated Exmor R CMOS; about 33.0 MP effective (34.1 MP total)

Back illumination moves the wiring behind the light-sensitive layer, helping reduce noise in low light.

Sony
AutofocusFast Hybrid AF; 759 phase-detection points for stills, 495 for movies; AI recognition of humans, animals, birds, insects, cars, trains and aeroplanes; EV -3 to 20

Hybrid AF combines phase detection with contrast detection. The recognition function finds and tracks the selected subject type in the frame; the user chooses the subject type manually.

Sony		Fast Hybrid AF; 759 phase-detection points (full frame); EV -4 to 20; human, animal and bird eye detection (stills and movies)

Phase-detection points track the subject quickly; eye detection locks focus on the eye of moving people and animals.

Image stabilisationSensor-shift 5-axis stabilisation; 5.0 stops (CIPA)

The 5-stop figure is pitch/yaw correction measured by Sony to the CIPA standard with the FE 50 mm F1.2 GM lens; it varies by lens and focal length. In video, Active mode crops the image slightly for stronger stabilisation.

Sony		5-axis sensor shift; 5.5 stops (CIPA)

The figure is measured with the Planar T* FE 50 mm F1.4 ZA for pitch/yaw only; it varies by lens and conditions.

Shutter and burstMechanical 1/4000–30 s, electronic 1/8000–30 s; flash sync 1/160 s; Hi+ 11 fps; buffer 59 RAW, 143 JPEG Extra Fine frames

The buffer figure is the approximate number of frames the camera can shoot in a row before waiting to write to the card.

The 120 fps finder setting shows a smoother view when following moving subjects.

Sony
Screen3.0-inch touch TFT; 1,036,800 dots; side-opening vari-angle (176° opening, 270° rotation)

The side-opening screen can be turned to face forward so the user can see themselves when shooting selfies and vlogs.

Video4K up to 119.88p in 10-bit 4:2:2 (XAVC S/HS 280 Mbps); XAVC S-I 4K 59.94p at 600 Mbps; Full HD 119.88p; 4-channel 24-bit audio

10-bit 4:2:2 recording keeps more tonal information for colour grading. XAVC S-I compresses each frame separately for easier editing, but files are very large. Four-channel audio requires a compatible Multi Interface Shoe microphone.

Sony		Up to 4K 60p/50p in 10-bit 4:2:2; XAVC HS (H.265) up to 200 Mbps, XAVC S (H.264) up to 200 Mbps, XAVC S-I up to 600 Mbps

XAVC S-I compresses each frame individually; it is easy to edit but takes much more space. 10-bit 4:2:2 reduces banding when grading.

Sony
Card slotSingle SD slot; UHS-I and UHS-II

A UHS-II card helps with high-bitrate video and clears the buffer faster after long bursts. There is no second slot for backup recording.
