Next-generation mirrorless video flagship arrives Fuji X-T4 in-depth evaluation

  This article comes from Hummingbird.

   For imaging products, what many users want is a product that can solve all their needs in one machine, that is, they want powerful performance, and they want to have a high-value appearance. Lightweight and portable. In the early days, this seemed like a fish and a bear’s paw. If you need powerful performance, you may sacrifice all the features of lightness and portability. It seems that this problem is still unsolvable.

   really no Solution? The X-T3 launched by Fuji in September 18 seems to be trying to break this “curse”. The appearance of the X-T3 is indeed amazing. It is said that the X-T3 redefines the flagship model of the APS-C format mirrorless camera. For over. However, the law of development of the camera industry is continuous progress, and users will always look forward to more. I have to admit that it is not easy to take a step forward on a very good model, but Fuji has done this. In February of this year, Fuji brought a new generation of flagship model-X-T4, and my impression of this machine is obviously that the performance of this machine is quite balanced, which can be called the flagship product of the next era APS-C.

   Fuji X- T4 vs. Fuji X-T3

  From these figures and specifications alone, the upgrade of Fuji X-T4 is still very eye-catching, whether it is the addition of body anti-shake and the increase in continuous shooting speed, It is also the improvement of the display specifications and the stronger endurance brought by the new battery. All these improvements are the icing on the cake for the X-T4. Although sensors and processors are still old faces, they are enough to show the strength of this 26.1 million pixel X-TransCMOS4 and X-Processor4 pair of golden partners.

Appearance of   Fuji X-T4

   Compared with X-T3, Fuji X-T4 has an increase in body size, which is mainly reflected in the thickness. The reason for the increase in thickness Mainly due to the addition of body anti-shake. But the increase in the thickness of the fuselage did not significantly affect the portability of the whole machine.

   Fuji X- T4 front

  X-T4 is still the classic retro look you are familiar with, but it has been fine-tuned in the details. From an overall point of view, the overall texture of the Fuji X-T4 is very good, and the workmanship is also very solid. Like the X-T3, the X-T4 also has two color combinations, namely vintage silver and pure black. This one is vintage silver. It looks really “inner taste”. From the details, the biggest change in the front of the fuselage is obviously in the warship, which has been fine-tuned in design.

   When it comes to the back of the fuselage, there seems to be no change at first glance, but it is not. The first is the change in the layout of the buttons. The positions of the Q key, auto meter lock and auto focus lock are all adjusted. In addition, the function of the dial on the top of the machine has also been adjusted.

   The left shutter mode dial is in addition to the traditional single In addition to shooting and continuous shooting, a new HDR mode has been added, and the video mode on the X-T3 has also been removed-now the right dial on the X-T4 can quickly switch between photo and video modes. In addition to the change of the dial, I believe that the more obvious change that everyone will notice on the X-T4 is obviously the new LCD screen.

  Fuji X-T4 screen

   Fuji X-T4 adopts a newly designed eversion A flip screen, which means that this screen has a larger flip range, which is more convenient for viewing from different angles or for selfies. And this screen has also been improved in terms of parameters, now it has been increased to 1.62 million pixels. In addition to the energy-saving mode, the X-T4 body also provides three enhancement modes for this LCD screen: low light priority: allows you to work in low light The subject can be clearly seen from below; resolution priority: even the fine details of the subject can be displayed; frame rate priority: the blur in the viewfinder can be minimized when shooting moving objects.

   Fuji X- T4 interface part

   The left side of the fuselage is its interface part, from top to bottom are the microphone interface, remote control interface, miniHDMI interface and USBType-C interface. It seems that Fuji has cancelled the 3.5mm headphone jack, but it provides a Type-C to 3.5mm headphone jack in the X-T4 package, which meets the user’s monitoring needs to a certain extent. And the design of the interface cover has also been adjusted, and now there is a clear partition.

   Fuji X- The bottom of the T4 machine

   The bottom of the fuselage is the battery compartment and the handle interface. It is worth mentioning that the quick release board interface of Fuji X-T4 is more intimate in position design and will not conflict with the position of the battery compartment. Of course, the bigger point is that the X-T4 is replaced with a battery model of NP-W235. Compared with the NP-W126S used on the X-T3, its battery capacity is increased by 1.5 times, reaching 2200mAh. This allows the Fuji X-T4 to take 500 pictures per charge in normal mode, 600 pictures in power saving mode, and battery life can be increased to 1,700 pictures when used with the optional handle.

   Generally speaking, the appearance of Fuji X-T4 is not very obvious. , But its internal improvement is still very solid. The new flip screen can meet more shooting needs, and the new battery also improves the endurance of the whole machine.

  Sensitivity real shot test

   I believe that many users will care about the sensitivity performance of this flagship model. Fuji X-T4 is equipped with a 26.1 million pixel back-illuminated X- TransCMOSIV sensor, with X-Processor4 image processing engine, the ISO range is ISO160-12800, which can be expanded down to ISO80 and up to ISO51200. Since there is no software that can correctly decode the RAW files of the Fuji X-T4, this test uses the JPG files directly from the camera, and the level of “High ISO noise reduction” is adjusted to “-4” in the camera settings. “To try to reduce the impact of in-camera processing on image quality.

Next-generation mirrorless video flagship arrives Fuji X-T4 in-depth evaluation

  We are this time What we tested is the sensitivity range of ISO80-6400, which is commonly used by everyone. It needs to be emphasized again that this time we used the camera’s JPG file for comparison. We set the “High ISO noise reduction” option in the camera to “-4” in order to minimize the impact of the in-camera processing on the high performance performance. From a comparison point of view, when the sensitivity is ISO1600, there is a slight smearing feeling, and when it reaches ISO6400, although the smearing and grainy feelings are improved, the details are relatively more retained, and the usability is higher. .

  Focus and continuous shooting test

   Fuji X-T4 adopts a new shutter mechanism and a newly developed high-torque coreless DC motor. The shutter can be used in continuous shooting mode Shooting at 15 frames per second, the electronic shutter has reached 20 frames per second. If there is a higher demand, it can reach a speed of 30 frames per second at 1.25x cropping.

   In addition, Fuji X-T4 also has an internal function that can be further improved-focusing performance. Fuji said that the X-T4 uses a new algorithm and phase detection autofocus function, which improves the autofocus performance to 0.02 seconds. In addition, the X-T4’s tracking autofocus performance has been significantly improved. The new algorithm uses color information and the shape of the subject to lock and stably track the moving subject, thereby maintaining precise and instant focus. I also shot a focus tracking video when shooting animals to show its performance. You can see that the focus frame is always moving with the movement of the animals.

   In addition, the X-T4’s face/eye autofocus performance has also been updated, and the current ability to track faces and eyes in continuous shooting mode is about twice as much as before. And the auto focus system in X-T4 can work in almost dark environment as low as -6.0EV.

   For the eye-controlled focusing that everyone cares about, we have also experienced it through real shooting. What you can see is that the camera can quickly recognize the face and the existence of the face, even if the character is short After leaving the viewfinder, the person can be identified and focused in time when the person reappears. In our video, even if the person has a large range of motion, it can still ensure accurate focus.

   Anti-shake effect test

   One of the highlights of X-T4 this time is obviously the built-in body anti-shake, X-T4 is the first equipped machine in the XT series micro-single Model with body stabilization. When used with 18 of 29 XF/XC lenses, it can provide up to 5-axis image stabilization performance of 6.5 gears, and its detection accuracy is about 8 times that of the X-H1’s body anti-shake unit. The device is useful for night photography or action photography such as sports, and also helps to easily record video in situations where camera shake is prone to occur. The new body anti-shake unit uses magnetic force instead of a spring, which not only improves its performance, but also makes it 30% smaller and 20% lighter than the X-H1’s image anti-shake device. Let’s test the anti-shake effect of X-T4 in photo shooting and video shooting respectively.

Next-generation mirrorless video flagship arrives Fuji X-T4 in-depth evaluation

   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 XF16-80mmF4ROISWR, which Fuji calls this lens. With X-T4 body, it can achieve up to 6-speed compensation effect. We chose its 80mm telephoto end for testing. In the test, I set the camera to the shutter priority gear, starting from the safe shutter speed, reducing the shutter speed step by step to shoot, and taking 3 photos at the same time at each shutter speed to see whether the satisfactory anti-shake effect is achieved.

Next-generation mirrorless video flagship arrives Fuji X-T4 in-depth evaluation

   During the real shooting test, 3 shots were taken at each shutter speed Among the photos, if there are 2 clear photos, it is considered that the usability at the shutter speed is high. In the real shot test, I found that when the Fuji X-T4 with XF16-80mmF4ROISWR is 1/2s, the photo appears blurry due to the jitter exceeding the anti-shake compensation effect, so it is judged that the anti-shake compensation of this lens is about 5-6 gears Left and right, in line with Fuji’s nominal numbers.

   In the video mode, in addition to the combination of body anti-shake and lens anti-shake, X-T4 also provides DIS digital anti-shake and a more powerful image stabilization enhancement mode , But because X-T4 suggests that the image stabilization boost mode is suitable for static handheld shooting, we did not use it in this video.

   After turning on the video anti-shake function, you can clearly see that the jitter of the Fuji X-T4 screen will be reduced. After the addition of digital anti-shake, although the viewing angle is lost, the anti-shake effect is More obvious. According to the needs of readers, I also specially take screenshots to show the effect of different camera anti-shake modes on the screen cropping. It should be noted that the default screen cropping factor for 4K/60P video is 1.18*.

   video recording The effect of different anti-shake modes on screen cropping

   Overall, the body anti-shake mechanism of the Fuji X-T4 has an excellent performance, whether it is in photo shooting or video shooting. For Fuji X-T4, this mechanism obviously greatly improves the usability of handheld shooting. With X-T4’s new flip screen, powerful video performance and this set of anti-shake mechanism, X-T4 can also become a Excellent VLOG video artifact.

  Video performance

   Since the powerful video performance was mentioned in the previous article, we might as well experience it through real shooting. Like X-T3, X-T4 also supports H.264/MPEG-4AVC and H.265/HEVC formats, and can record 4K/60P video up to 4:2:010bit, with a bit rate up to 400Mpbs. HDMI can output uncompressed 4:2:210bit4K/60p video.

   In addition, X-T4 can now shoot 1080P/240P video, which can generate up to 10 times slow-motion video.

   In addition, the Fuji X-T4 continues the ability to record F-Log in the camera. If you want a larger dynamic range, you can use F-Log directly. For the convenience of monitoring, X-T4 It also provides the F-Log auxiliary viewing function. During the F-Log recording, the file can be converted into a video equivalent to BT.709 for display.

  Sample real shooting

   Over the years, Fujifilm’s color science has been refined through the research and development of analog and digital photography. Fuji X-T4 can call a total of 18 film simulations in both photo shooting and video recording. In addition to ClassicNeg, which debuted on X-Pro3. Classic negatives are also included in X-T4, Fuji X-T4 Also equipped with new ETERNA. The BLEACHBYPASS effect, which can present a high-contrast effect while maintaining low color saturation, faithfully reproduces the film processing technology called “bleaching effect”. The lens used in this group of samples is also XF16-80mmF4ROISWR. The pictures that are not marked with film simulation in the sample use PROVIA/standard film simulation

   In addition to the appearance of the Fuji X-T4 is very textured, the samples taken also left a deep impression on me. Regarding the shooting experience of the Fuji X-T4, it is obvious that color, color and color have to be mentioned. The unique and self-adjustable color style is believed to be the reason why many users choose Fuji. Film simulation brings an experience that can be shared almost without post-production. The X-T4’s powerful performance is the best guarantee for this relaxed performance.

  Editor’s View

   Fuji X-T4 looks very similar to X-T3 at first glance. The retro style design ideas have been implemented, and its classics can be seen today. For me, the appearance of the Fuji X-T4 is obviously nothing but beautiful, and it can be described as the forefront of the camera appearance ranking in my mind. However, this camera is far superior to the X-T3. Obviously the biggest aspect of this mirrorless camera is the anti-shake of the body. The anti-shake of the X-T4 is compared with the previous generation in terms of size and performance The body image stabilization product can be greatly improved, and the upgrade of the focus performance makes the experience of using this camera even better. Of course, the 26.1 million pixel X-TransCMOS4 sensor and the X-Processor4 processor match, so that this camera has a very powerful performance in both photo shooting and video recording.

  In terms of volume, the small-frame M4/3 micro-single or even one-inch products are obviously better, but they are inferior in terms of image quality. Although the full-frame camera can theoretically be The quality and other aspects are better, but losing the advantage of small size will make those users who are concerned about size and weight hesitate. The APS-C format Fuji X-T4 is a good balance between these two points, and the Fuji X-T4 has been improved on the basis of the already very powerful X-T3 itself, in the shooting of still images and videos. I also have a better experience, and with outstanding performance in these areas, I even think that the X-T4 can be compared with the professional cameras on the market. Moreover, Fuji now has a very rich lens group in the field of APS-C format mirrorless lenses. With such a comprehensive lens group, it is also an important guarantee for realizing the full output of the X-T4 camera.
