FUJIFILM X-T50 / Sony α7 IV (ILCE-7M4)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

The weight does not include a lens.

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

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

Fujifilm does not list weather resistance for the body.

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

Fast cards are needed for high-bitrate S&Q and S-I recording.

USB PD lets the camera run from a power bank or adapter during long shoots.

The coating aims to reduce dust sticking to the sensor; Sony gives no moisture-resistance rating on this page.
