For professional camera, many users want to be able to solve all the needs of the product in one machine. That is, they want to have strong performance, high beauty housing, and also want to be light and portable. In the early days, this seemed very difficult. If you need strong performance, you may sacrifice the characteristics of light and portable. It seems that the problem is still unsolved until Fujifilm X-T3. Now is X-T4.

The X-T3 launched by Fujifilm in September 2018 seems to be trying to break the “magic spell”. The appearance of X-T3 is really amazing, and it can not be overemphasized to say that X-T3 redefines the flagship model of APS-C painting micro SLR. However, the development law of camera industry is continuous progress, and users are always looking forward to more. One thing we have to admit is that it is not easy to go further on a very good model, but Fujifilm did exactly that. In February 2020, Fujifilm brought a new generation of flagship model, the X-T4. My impression of this machine is that it has a fairly balanced performance and can be called the new APS-C flagship product.

From the specifications comparision figure, the upgrade of Fuji x-t4 is still very eye-catching. Whether it’s the addition of body anti shake, the increase of continuous shooting speed, the improvement of display screen specifications, and the stronger endurance capability brought by the new battery, all these improvements are great for x-t4. Although sensors and processors are old-fashioned, they are enough to show the strength of the 26.1 megapixel x-trans CMOS 4 and x-processor 4.

Fuji X-T4 Appearance

Compared with the x-t3, the size of Fuji x-t4 has increased, which is mainly reflected in the thickness. The main reason for the increase in thickness is the addition of anti shake. However, the increase in the thickness of the fuselage does not significantly affect the portability of the whole machine.

The x-t4 is still a classic retro look you’re familiar with, just fine-tuning the details. On the whole, Fuji x-t4 has excellent texture and solid workmanship. It’s the same as x-t3. X-t4 also has two colors, retro silver and pure black. This one is retro silver. It looks like it has a real “flavor”. In terms of details, the biggest change in the front of the fuselage is obviously at the warship, with fine-tuning in design.

When it comes to the back of the fuselage, at first glance it seems that there is no change, but in fact it is not. The first is the change of key layout. The positions of Q key, auto metering lock and auto focus lock are all adjusted. In addition, the functions of the dial on the set top are also adjusted.

In addition to the traditional single shot and continuous shot, the left shutter mode dial has also added a new HDR mode, and the recording mode on the x-t3 has also been removed – now the right dial on the x-t4 can quickly switch between the shooting and recording modes. In addition to the change of dial, I believe you will notice that the more obvious change of x-t4 is obviously the new LCD screen.

Fuji x-t4 LCD

Fuji x-t4 adopts a newly designed flip-over screen, which means that the flip range of this screen is larger, and it will be more convenient for viewing from different angles or for self shooting. Besides the energy-saving mode, the x-t4 body also provides three special enhancement modes for this LCD screen: low light priority: allowing you to see the subject clearly in low light; resolution priority: even displaying the fine details of the subject; frame rate priority: when shooting the moving subject, you can try your best Reduce blurring in the viewfinder.

Fuji x-t4 Interface

The left side of the fuselage is the interface part, from top to bottom are microphone interface, remote control interface, mini HDMI interface and USB type-C interface. It seems that Fuji cancelled the 3.5mm headphone interface, but provided a type-C to 3.5mm headphone interface in the x-t4 package, which to a certain extent met the user’s needs in monitoring. And the design of the interface cover has also been adjusted, and now there is a clear division.

In terms of storage, Fuji x-t4 is also worth mentioning that it is equipped with a dual SD card slot supporting USM-II standard, which can realize high-speed reading and writing, which also contributes to the powerful performance of the new camera, and the use of the dual SD card slot also reduces the user’s storage and use cost.

Bottom of Fuji X-T4

At the bottom of the fuselage is the battery compartment and the handle interface. It is worth mentioning that Fuji x-t4’s quick release board interface is close to each other in position design, and will not conflict with the position of the battery compartment. Of course, the bigger point is that the x-t4 uses a NP-W235 battery. Compared with the NP-W126S used on the x-t3, its battery capacity is increased by 1.5 times, reaching 2200mAh, which enables Fuji x-t4 to take 500 pictures per charge in normal mode and 600 pictures in power saving mode. When it is used with the optional handle (two batteries), it can continue to take The number of flights can be increased to 1700.

In general, although the appearance of Fuji x-t4 has not changed significantly, its internal improvement is still solid. The new flip screen can meet more shooting needs, and the new battery also improves the endurance of the whole machine.


It is believed that many users will care about the photosensibility performance of this flagship model. Fuji x-t4 is equipped with a 26.1 million pixel backlight x-trans CMOS IV sensor and x-processor 4 image processing engine. The ISO range is ISO160-12800, which can be expanded down to ISO 80 and up to ISO 51200. At present, there is no software that can correctly solve the raw file of Fuji x-t4, so this test uses the JPG file directly out of the camera, and adjusts the level of “high ISO noise reduction” to “- 4” in the camera settings, so as to reduce the impact of the internal processing on the image quality as much as possible.

Photosensibility of Fuji X-T4

What we are testing this time is the sensitivity category of ISO80-6400, which is commonly used. It needs to be emphasized again that the JPG file of the fuselage is used for comparison. We set the option of “high ISO noise reduction” to “- 4” in the fuselage to minimize the impact of internal processing on high-sensitivity display. In contrast, when the sensitivity is iso1600, there is a slight smear feeling, and when it reaches ISO 6400, although the smear sense and particle sense are improved, there are relatively more details retained, with a higher availability.

Focus and Continuous Shooting

Fuji x-t4 adopts a new shutter mechanism and a newly developed high torque coreless DC motor. The shutter can shoot at 15 frames per second in continuous shooting mode, and the electronic shutter can shoot at 20 sheets per second. If there is a higher demand, the speed of 30 sheets per second can be achieved at 1.25 times of cutting.

In addition, Fuji x-t4 also has an internal skill that can be further improved – focusing performance. Fuji claims that x-t4 adopts a new algorithm and phase detection auto focus function, which improves the auto focus performance to 0.02 seconds. In addition, the tracking auto focus performance of x-t4 is significantly improved. The new algorithm uses the color information and the shape of the subject to lock and track the moving subject stably, so as to maintain accurate and instant focus. I also shot a video of the animal’s focusing to show its performance. I can see that the focusing frame is always moving with the animal’s movement.

In addition, the auto focus performance of face / human eye of x-t4 has also been updated. At present, the ability of tracking face and human eye in continuous shooting mode is about twice as much as before. And the auto focus system in x-t4 can work in a dark environment as low as – 6.0EV.

As for the eye control focusing that you are concerned about, we have also experienced it by taking real pictures. What we can see is that the camera can quickly recognize the existence of the face and the face. Even after the character leaves the view range for a short time, it can recognize and focus in time when the character reappears. And in our video, even if the person has a relatively large range of motion, according to the Old can ensure accurate focus.


One of the highlights of the x-t4 is that it has built-in anti shake body. X-t4 is the first anti shake body model in the x-t series of micro slips. When it is used with 18 of 29 XF / XC lenses, it can provide up to 5-axis 6.5-gear image anti shake performance, and its detection accuracy is about 8 times of that of the anti shake unit in x-h1. The device can be used for action photography such as night photography or sports photography, and also can be used for easily recording video when camera shake is easy to occur. The new body anti shake unit uses magnetic force instead of spring, which not only improves its performance, but also makes it 30% smaller and 20% lighter than the image anti shake device of x-h1. Let’s test the anti shake effect of x-t4 in picture shooting and video shooting respectively.

Fuji x-t4 is equipped with a newly designed body anti shake mechanism

First of all, let’s take a look at the anti shake effect under the picture shooting. This time, the lens with x-t4 is XF16-80mm F4 R OIS WR. Fuji nominally, this lens with x-t4 body can achieve the compensation effect of up to 6 gears. We choose the 80mm (equivalent 35mm focal length is 120mm) long focal end to test. In the test, I set the camera as the shutter priority position, start from the safe shutter speed and reduce the shutter speed one by one, and take 3 photos at the same time at each shutter speed to see whether the satisfactory anti shake effect is achieved.

In the real shooting test, 2 of the 3 photos taken at each shutter speed are clear, which indicates that the availability at this shutter speed is high. In the real shooting test, I found that when Fuji x-t4 is matched with XF16-80mmF4 R OIS WR for 1 / 2S, due to the jitter exceeding the anti shake compensation effect, the photo is blurry, so it is judged that the anti shake compensation of this lens is about 5-6, which is in line with Fuji’s nominal number.

In the video mode, in addition to the combination of the anti shake of the fuselage and the anti shake of the lens, x-t4 also provides dis digital anti shake and a more powerful image stable energy increasing mode. However, because x-t4 indicates that the image stable energy increasing mode is suitable for static handheld shooting, we do not use it in this video frequency. We also make a comparison through video live shooting.

After the video anti shake function is turned on, it is obvious that the image jitter of Fuji x-t4 will be reduced. After the digital anti shake function is added, although the viewing angle is lost, the anti shake effect is more obvious. According to the needs of the readers, I also specially take screenshots to show the impact of different anti shake modes of the fuselage on the image cutting. You should note that the default image cutting coefficient of 4K / 60p video is 1.18 ×.

The influence of different anti shake modes on picture cutting ratio in video recording

In general, the anti shake mechanism of Fuji x-t4 has outstanding performance, whether in photo shooting or video shooting. For Fuji x-t4, this set of mechanism obviously greatly improves the availability of hand-held shooting. With the new flip screen of x-t4, strong video performance and this set of anti shake mechanism, x-t4 can also become an excellent vlog video artifact.

Video Performance

Since we mentioned the strong video performance in the previous article, we might as well experience it through real-time shooting. As with x-t3, x-t4 also supports H.264/MPEG-4 AVC and H.265/HEVC formats, and can record 4K / 60p video of up to 4:2:0 10bit, with a code rate of up to 400Mpbs, and HDMI can output 4:2:2 10bit 4K / 60p video without compression.

In addition, x-t4 can now shoot 1080P/240P video, which can generate up to 10 times of slow motion effect video.

In addition, Fuji x-t4 continues the ability to record F-Log in the machine. If you want a larger dynamic range, you can use F-Log directly. In order to facilitate monitoring, x-t4 also provides F-Log auxiliary viewing function. During F-Log recording, you can convert files to videos equivalent to BT.709 for display.

Sample Photography

Over the years, research and development in analog and digital photography refined the color science of Fujifilm. Fuji x-t4 can call a total of 18 film simulations in both picture shooting and video recording. In addition to the classic neg, which debuted on X-Pro3 for the first time, the classic negative film is also included in x-t4, Fuji x-t4 also carries a new eterna. Clean bypass effect, which can maintain low color saturation and present high contrast effect, faithfully reappears the film processing technology known as “bleaching effect”. The lens of this group of samples is also XF16-80mm F4 R OIS WR. The picture without film simulation in the sample film is simulated with PROVIA/standard film.

In addition to the appearance and texture of Fuji x-t4, I was deeply impressed by the samples taken. About the shooting experience of Fuji x-t4, it is obvious that we have to mention color, color and color. The unique and self-adjusting color style is believed to be the reason for many users to choose Fuji. Film simulation brings an experience that can be shared almost without later stage after straight out. The x-t4’s powerful performance is the best guarantee for this easy performance.


Fuji x-t4 looks like x-t3 at first glance. The design idea of retro modeling has been implemented so far, and its classics can be seen. For me, the appearance of Fuji x-t4 is obviously pretty, which is in the forefront of camera beauty ranking in my mind. However, this camera is far superior to the x-t3. Obviously, the most important point of this micro single is the anti shake of the fuselage. The anti shake of the fuselage on the x-t4 is greatly improved in volume and performance compared with that on the previous generation of anti shake products. The upgrade of focusing performance makes the experience of using this camera better. Of course, the combination of the 26.1Megapixel X-Trans CMOS 4 sensor and X-Processor 4 processor makes this camera have very powerful performance in both photo shooting and video recording.

In terms of volume, the M4/3 micro SLR or even one inch products with small picture size are obviously more excellent, but they are inferior in terms of image quality and other aspects. Although the full picture camera can be better in terms of image quality and other aspects in theory, it will make those users who consider volume and weight hesitate to lose the advantage of small size. The Fuji x-t4 of APS-C picture is a good balance of these two points, and Fuji x-t4 has been improved again on the basis of x-t3 itself, and has a better experience in still image and video shooting, and these excellent performances, I even think that x-4 can be compared with professional cameras on the market. And Fuji now has a very rich lens group in the APS-C frame micro single field. With such a comprehensive lens group, it is also an important guarantee to achieve the full output of the x-t4 camera.

Now Fujifilm X-T3 is hot sale on amazon.com with Best Price, shopping now. Hope X-T4 launch soon.
