Sensor35.6 × 23.8 mm full-frame CMOS; 24.1 MP effective, 26.8 MP total Panasonic23.5 × 15.7 mm APS-C X-Trans CMOS 5 HR; 40.2 MP effective

The same sensor is used in the X-T5 and X-H2; the high resolution leaves room to crop but makes files larger.

Fujifilm
Lens mountLeica L-Mount PanasonicFUJIFILM X

Directly compatible with X-series XF and XC lenses; GF lenses do not fit this body.

Fujifilm
Still image size3:2, up to 6000 × 4000 Panasonic—
High-resolution mode3:2, up to 12000 × 8000; multi-shot mode Panasonic—
FilesJPEG, HEIF, RAW; MP4 and MOV video options PanasonicJPEG, 10-bit 4:2:2 HEIF, 14-bit RAF RAW; TIFF only from in-camera RAW conversion

HEIF stores more colour gradations than JPEG; RAW gives the most flexibility when editing.

Stabilization5-axis sensor shift; Dual I.S.2 compatibility Panasonic—
AutofocusImage-plane phase detection + contrast detection PanasonicIntelligent hybrid phase + contrast detection; face/eye plus animal, bird, car, motorcycle, airplane and train detection

Subject detection finds the chosen subject type in the frame and tries to keep focus on it.

Fujifilm
Viewfinder0.5-inch OLED, 5.76 million dots; approximately 0.78× Panasonic0.39-inch OLED; about 2.36 million dots; 0.62× magnification; 100% coverage

Magnification describes how large the viewfinder image appears; the X-T5’s viewfinder has a higher resolution.

Fujifilm
Monitor3-inch, 3:2 touchscreen; 1.84 million dots Panasonic—
USBUSB-C, 10 Gbit/s; USB PD 9 V / 3 A PanasonicUSB-C (USB 3.2 Gen 2x1)

USB 3.2 Gen 2x1 transfers up to 10 Gbit/s; it is used for file transfer and tethered shooting.

Fujifilm
HDMIFull-size Type A; RAW video output PanasonicMicro HDMI (Type D)

Micro HDMI is a small, fragile connector; securing the cable is advisable when connecting an external recorder.

Fujifilm
AudioSeparate 3.5 mm microphone and headphone; 2.5 mm remote Panasonic3.5 mm microphone input; USB-C adapter in the box for headphones

There is no separate headphone jack on the body; video audio is monitored through the adapter.

Fujifilm
External recordingExternal SSD recording support Panasonic—
Dimensions134.3 × 102.3 × 91.8 mm; excluding protrusions Panasonic123.8 × 84 × 48.8 mm (34.2 mm at the thinnest point)

Depth is measured including the grip; the lens is not included.

Fujifilm
Weight800 g with battery and one SD card; 718 g body only PanasonicAbout 438 g with battery and card; body about 389 g

The weight does not include a lens.

Fujifilm
WirelessWi-Fi 802.11a/b/g/n/ac; Bluetooth 5.0 LE PanasonicWi-Fi 802.11a/b/g/n/ac; Bluetooth 4.2 low energy

Bluetooth keeps the phone paired and passes location data, while Wi-Fi handles photo transfer.

Fujifilm
Operating range−10–40 °C; splash resistant, not for submersion Panasonic—
Processor—X-Processor 5

The image processor that runs the autofocus algorithms, film simulations and video encoding.

Fujifilm
Image size—3:2 up to 7728 × 5152

This is the pixel size of the largest photo at the sensor’s full resolution.

Fujifilm
Standard ISO—125–12,800; extended 64–51,200

Extended ISO values may reduce dynamic range or add noise; the maker counts them outside the standard range.

Fujifilm
Stabilisation—5-axis sensor shift; up to 7.0 stops; additional digital stabilisation for video

Sensor shift reduces shake even with unstabilised lenses; digital stabilisation crops the image slightly.

Fujifilm
Shutter—Mechanical 4 s (30 s in A mode) to 1/4000 s; electronic up to 1/180,000 s; flash sync 1/180 s

The electronic shutter is silent and allows very short exposures, but fast-moving subjects can appear skewed.

Fujifilm
Burst shooting—Mechanical about 8 fps; electronic 13 fps uncropped, 20 fps with a 1.29× crop

In the 20 fps mode speed drops after 168 JPEGs or 66 compressed RAW frames; buffer depth depends on file type.

Fujifilm
Film simulation—20 modes; dedicated film simulation dial on the top plate

Film simulations change the colour and tone of JPEG and HEIF files; a RAW file can be processed later with a different simulation.

Fujifilm
Card—Single SD/SDHC/SDXC slot; UHS-I and UHS-II, V90

With a single slot, recordings cannot be backed up to two cards at once.

Fujifilm
Rear screen—3-inch tilting touch LCD; about 1.84 million dots

The screen tilts up and down; it does not flip to the side and face forward, so you cannot see framing when filming yourself.

Fujifilm
Video—6.2K 29.97p; 4K 59.94p; Full HD up to 240p; MOV H.265 with 24-bit/48 kHz PCM audio

Fujifilm lists about 45 minutes of continuous recording in 6.2K and 4K with face detection off; this may vary with temperature.

Fujifilm
Flash—Pop-up built-in flash; TTL-compatible hot shoe

The built-in flash can trigger external flashes in commander mode.

Fujifilm
Battery—NP-W126S lithium-ion; about 305 frames in normal mode and about 390 in economy mode

The frame count was measured by Fujifilm with the XF35mmF1.4 R; it is clearly lower than with the X-T5’s larger NP-W235 battery.

Fujifilm
In the box—NP-W126S battery, USB cable, headphone adapter, shoulder strap, body cap

No separate charger is listed; the battery charges in the camera over USB.

Fujifilm
Operating conditions—0–40 °C; 10–80% humidity (non-condensing)

Fujifilm does not list weather resistance for the body.
