Photography in Motion
Making a camera that suitable for both photography and videography is no simple task. The X-T4 is our most powerful X Series camera to date with no compromises for stills or video. Using the 4th generation X-Trans CMOS 4 sensor, X-Processor 4, a newly developed compact in-body image stabilization (IBIS) system, new Film Simulation mode “ETERNA Bleach Bypass” and various other features that have evolved based on user feedback, this camera delivers image quality that can satisfy the demands of professional photographers and videographers.
Colors
"Colors"matter every time
Film Simulation
FUJIFILM’s color science is a result of years of research in both analog and digital photography. All X Series cameras allow you to access this research at the touch of a button to help you express your creative vision. The X-T4 features the our new “color” expression, “ETERNA Bleach Bypass.” It produces a high-contrast look while keeping the level of color saturation low, faithfully reproducing a film processing technique called “bleach bypass,” which has been popular among many creative producers since the days of film photography.
Tone Adjustment
Highlight and shadow tones can be adjusted by 1/2 stops, instead of full stops, capturing scenes exactly as you have imagined them. This can be used in combination with Film Simulations, to significantly reduce post processing time.
Auto White Balance
The Auto White Balance(AWB) can be set to “AUTO,” “White Priority” or “Ambience Priority”. In scenes lit by incandescent bulbs, the camera would choose for whiter whites when set to “White Priority” and warmer whites when set to “Ambience Priority”.
Performance
Speed where you need it to capture the decisive moment
The X-T4 utilises the high-speed performance of the X Trans CMOS 4, which is a back-illuminated structure and features phase-detection pixels across the entire sensor. Combined with a new advanced AF algorithm and the X Processor 4, the camera delivers exceptional autofocus performance. The X-T4 has the ability to focus fast and accurately in low light, lock onto human face / eyes, and track a moving subject with ease providing you with added confidence to capture the decisive shot.

0.02 second AF
The new AF algorithm on the X-T4 gives an AF speed of up to 0.02 second; which is the fastest AF speed among mirrorless cameras with an APS-C size sensor.
The improved AF algorithm also allows you to capture your subject with an outstanding accuracy of over 90%. This evolved AF algorithm combined with the X-Trans CMOS 4 and the X Processor 4, gives professional level performance at every opportunity

Tracking AF
The tracking AF performance has been significantly improved. The new algorithm uses color information and the subject shape to lock on and steadily track a moving subject, maintaining accurate and instantaneous focus.
Face & Eye AF
The Face / Eye AF performance has been updated and is now around twice as good at tracking people’s face and eye while shooting in burst mode. The X-T4 will capture the face and eye even when the subject is constantly moving across the entire frame.

Low Light AF
The AF system in the X-T4 works down to -6.0EV, which is almost complete darkness. The phase detection AF system is fast and accurate even in these low light conditions.
Burst shooting
The new focal plane shutter unit in the X-T4 use a high-speed coreless DC motor. This enables a super-fast 15fps continuous shooting in post view*1 and an 8fps continuous shooting with live view. The shutter is also 30% quieter and offers twice the durability of previous models with 300,000 shutter actuations*2. The blackout period when using the live view burst mode has been shortened up to 75msec, and the release time lag is quick as up to 0.035second, promising you with an instantaneous response. When shooting with electronic shutter, you can shoot up to an incredible 30fps. Combined with the evolved AF performance, the shutter system makes it possible to capture the every moment, even when your subject is moving.

Durability
A camera that withstands the elements and ready when you are.
In body image stabilization
The image stabilization unit has been dramatically reduced in size (30% smaller and 20% lighter), without compromising the performance. The new unit uses magnets instead of springs and high-performance gyro sensors to improve accuracy 8 times better compared to what X-H1 adopted. Also, the new shock absorbing structure integrated in the image stabilization unit will stabilize the smallest shakes, allowing the new focal plane shutter unit to perform at its full potential. Finally, the unit carries out over 10,000 corrections per second to achieve up to 6.5 stops of image stabilization with 18 out of 29 FUJINON XF lenses.
Weather-Resistance
The X-T4 has 63 weather sealed points which gives it the advanced level of dust- and moisture resistance, similar to that of the X-T3.
 
You can shoot without concern, knowing that the camera operates in temperatures as low as minus ten degrees Celsius and in tough conditions like rain or in clouds of dust.
LCD/EVF
Boost mode
The X-T4 has three ‘Boost’ modes that changes the responsiveness of the LCD and EVF according to what you are shooting.
