Sensor35 mm full-frame Exmor R CMOS (35.9 × 23.9 mm); about 33.0 MP effective for stills, 27.6 MP for movies

Exmor R is a back-illuminated sensor; with the circuitry behind the light-sensitive layer it gathers more light in dim conditions.

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, 627 for movies; EV −4–20; human, animal, bird, insect, car, train and aeroplane recognition

Subject recognition finds the chosen type (for example a bird) in the frame and tracks its eye or body; choosing the right subject type in the menu strengthens tracking.

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.

Sony
Image stabilisationSensor-shift 5-axis stabilisation; 7.0 stops (CIPA)

Sony measures 7.0 stops with the FE 50 mm F1.2 GM lens on pitch and yaw only; the benefit can differ with other lenses and axes.

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.

ISO and shutterStills ISO 100–51200 (expandable 50–204800); mechanical shutter 1/4000–30 s, electronic to 1/8000 s; up to 10 fps continuous Sony—
Video4K up to 59.94p, 10-bit 4:2:2 with XAVC HS and XAVC S (up to 200 Mbps); up to 600 Mbps with XAVC S-I

DPReview says 4K 30p is downsampled from a full-width 7K readout, while 4K 60p is recorded in Super 35 (APS-C) mode with a 1.5× crop. 10-bit 4:2:2 reduces banding when grading colour.

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.

Card slotSingle SD slot, UHS-I/UHS-II compatible

With one slot there is no backup recording to two cards at once. High-bit-rate video needs a fast UHS-II card.
