Sensor and processorAPS-C (23.5 × 15.6 mm) X-Trans CMOS 4, 26.1 MP; X-Processor 5 Fujifilm—
Image stabilisation5-axis sensor shift; 7.0 stops per CIPA; digital stabilisation and IS Mode Boost for movies

The 7.0-stop figure was measured with the XF35mmF1.4 R lens on the pitch and yaw axes only; it may be lower with other lenses.

Fujifilm		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.

ShutterMechanical up to 1/4000 s, electronic up to 1/32000 s; flash sync 1/180 s Fujifilm—
BurstAbout 30 fps with the electronic shutter (1.25x crop) or 20 fps uncropped; about 8 fps with the mechanical shutter Fujifilm—
AutofocusHybrid (phase detection + contrast); down to −7 EV with the XF50mmF1.0; face/eye and subject detection (animal, bird, automobile, motorcycle/bike, airplane, train) Fujifilm693 phase-detection points in full frame; 567 phase + 25 contrast points in APS-C mode Sony
VideoUp to 6.2K at 29.97p; DCI 4K/4K up to 59.94p; up to 360 Mbps; 4:2:2 10-bit internal recording; HEVC/H.264

According to Fujifilm, actual recording time at 6.2K is about 85 minutes per battery. For heat during long recordings an optional cooling fan can be attached; the box includes the fan connector cover.

Fujifilm		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.

Viewfinder0.39-inch OLED, 2.36 million dots, 0.62x magnification Fujifilm0.64-inch Quad-XGA OLED, 9,437,184 dots, 100% coverage, approx. 0.90× magnification; 60 or 120 fps

The 120 fps setting shows moving subjects more smoothly in the finder at the cost of more battery drain.

Sensor—35 mm full-frame back-illuminated Exmor R CMOS; approx. 61.0 MP effective (62.5 MP total)

61 MP allows heavy cropping and large prints; in return files are big and call for fast cards and a capable computer.

Sony
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
ISO—Stills ISO 100–32000 (expanded 50–102400); movies ISO 100–32000 equivalent 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
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.
