We have compared the ultra popular Fuji X-T3 with the Fuji X-T4. So, in this Fuji X-T4 vs. Fuji X-T3 you will get detailed report of the new features we have in the new camera .

Image Stabilization
One of the most noticeable improvements we have in the new Fuji XT-4 camera compared to Fuji X-T3 is the introduction of a 5-axis image stabilization system. The Fuji X-T4 is able to compensate upto 6.5 stops of shutter speed. Not only that Fuji is also able to give us DIS (digital image stabilization), specifically for video. But while using DIS mode we have to face at least 1.1X crop factor while using that.
Fuji says that they are able to improve the IBIS accuracy by 8 times when compared to Fuji X-H1 camera.

The design of Hand-grip in both the camera remains almost same without any significant change.
Improved Shutter Mechanism
Fuji introduced a new shutter mechanism inside the Fuji X-T4 camera. With the help of new shutter mechanism the Fuji X-T4 camera is able to shoot 15 FPS continuous shooting mode (with AF/AE tracking). As we know the Mechanical shutter of Fuji X-T.3 camera is limited to 11 FPS per second.
If you need faster burst speeds, note that both cameras can go up to 20fps with the electronic shutter, or 30fps with the electronic shutter and crop mode (1.25x). The cropping issue isn’t a Fuji problem, Sony IMX 571 sensor crops images upto 1.25x while you move on @ 20 or 30 fps per second.

Video modes compared
As usual Fuji X-T4 and the Fuji X-T3 camera are able to shoot 4K up to 60p and 200Mbps. But while shooting 4K video at 60 fps we have to face crop 1.18x crop. If you are using both cameras at 4K up to 30 and 400Mbps we have to face no cropping issue. You can have 10-bit 4:2:0 for internal recording and 10-bit 4:2:2 via HDMI [external recorder].
10X SloMo Mode: With the new Fuji X-T4 camera we are able to shoot 10X slo Mo videos with an impressive shooting speed of 240 FPS. The X-T3 can do a maximum of 120fps, which is half that (5x slow motion effect). Note that the High Speed mode works with a 1.29x crop.
But recent update suggest – Upcoming Firmware update will uplift the Full HD frame rates to 240FPS, same as we have in the Fuji X-T4.

Reworked AF Algorithms
Fuji X-T4 camera features brand new AF algo inside it, If we believe Fuji official press text, the accuracy of the Fuji X-T4 camera is now improved over 2X compared to Fuji X-T3 camera.
‘The Fuji X-T4 AF lock speed is also improved under standard shooting conditions. The AF lock speed of Fuji X-T4 camera is now the same 0.02sec as we have in the Sony A6600 camera.

Larger Body
Larger Body Due to presence of image stabilization inside the camera, The Body of Fuji X-T4 camera is slightly Larger and thicker compared to the Fuji X-T3 camera.
- X-T3: 132.5 x 92.8 x 58.8mm, 539g
- X-T4: 134.6 x 92.8 x 63.8mm, 607g
The battery grip of the camera remains the same as its predecessor. The only noticeable change we have spotted in the button layout of the camera is AEL and Q buttons have switched positions.
New Display Screen
Instead of a tilting display screen, the camera now arrived with a vari-angle display screen which is now more user friendly and Vloggers will feel a bit more comfy with the camera. And not only that, they have also improved the resolution of screen to 1.6 Million dot from 1.04 of Fuji X-T3 display.

More Battery
The Fuji X-T4 camera arrived with brand new battery X-T4 (NP-W235) with a capacity of 2350mAh, if we compare it with Fuji X-T3 battery then we have double backup power compared to the predecessor.
Economy mode to Save More Power
Fuji added a new economy mode with the Fuji X-T4 camera , And with the eco mode you can shoot more than 600+ shots with a single charge without any issue.. But, Even while you are shooting under standard mode you can capture more than 500 shots with a single charge.
That;s really impressive when you compare it with the Fuji X-T3 camera, since the predecessor was limited to 390 shots only with a single charge.
There is a new battery grip designed for the new camera, the VG-XT4, to accommodate two NP-W235 batteries.
————————————-
Major improvements
We can write our video files simultaneously on both the cards. BTW, SD card failure isn’t a big issue nowadays. F-Log View Assist which allows you to display normal contrast and colours when recording with Log (F-Log is available on the X-T3 as well).
Both Fuji X-T3 and Fuji X-T4, have a 3.5mm audio input that can be used for microphones. On the X-T4 it doubles as a line input for other types of audio equipment.
USB-C adapter instead (included in the box). Is being used to monitor the audio level of the camera while recording. The feature was introduced with Fuji X-T30.
Verdict: If you already won Fuji X-T3 camera, then no need to invest your money again on Fuji X-T4, you should wait for Fuji X-T5. If you are planning to buy a new Fuji X-T series camera than for sure go with the new Fuji X-T4 camera.
