In early September, Fuji released a new unveiled camera X-T3. It does not have the body's body five-axis anti-shake function on X-H1, but the first use of BSI sensor (X-Trans CMOS 4 back sensor) Anti-camera. Can BSI-CIS bring to X-T3 increased, in the existence of flagship X-H1, is the camera worth buying?
4 years later, BSI
The X-T3 is not the first APS-C brunette digital camera using the BSI sensor. It has previously released the first APS-C box in 2014, BSI sensor camera NX1. NX1 uses a 65nm copper interconnect process, 28 MP sensor, the highest continuous shooting speed is 15FPS, supports 4K / 30P, which subsequently released NX500 uses the same piece of sensor.
The X-T3 fuselage is basically X-T2 small change, operation, and feel different.
Therefore, X-T3 is the third model using the APS-C frame camera using the BSI sensor. It uses a custom version of Sony IMX571 sensor, built-in ADC maximum support 16bit accuracy (@ 6.84fps, X-T3 only support 14bit RAW format, shooting When the ADC accuracy is not clear), the total pixel is 26.78MP, the effective pixel 26.1MP, the highest continuous shooting speed under full pixels is 20fps, the mechanical shutter is reduced to 11FPS, 1.25X cut mode (16.6MP) Under the continuous shooting speed up to 30fps Support for pre-shooting (in front of the shutter, the camera will not stop shooting photos with electronic shutters, write cache.) X-T3 pixels are slightly lower than NX1, but the connecting speed, ADC accuracy is far better.
The X-T3 sensor has seen the phase difference to the focal area.
Full-pixel 11fps, 1.25X Cut 30FPS is only part of the X-T3 continuous shooting mode, in order to excavate the IMX571 sensor potential, Fuji designed multiple continuous shooting mode, specific continuous shooting speed, number of sheets, and restrictions :
About 30 / second [only for electronic shutters, 1.25 times crop] (JPEG: 60); non-destructive compression RAW: 35; uncompressed RAW: 33)
About 20 / sec [Electronic shutters only, 1.25 times cut] (JPEG: 114); lossless compression RAW: 37; uncompressed RAW: 34)
About 10 / sec [only electronic shutter, 1.25 times crop] (JPEG: 500); non-destructive compression RAW: 48; uncompressed RAW: 39)
About 20 / sec [JPEG: 79] (JPEG: 79; lossless compression RAW: 36); uncompressed RAW: 34)
About 11 / sec (JPEG: 145; lossless compression RAW: 42); uncompressed RAW: 36)
About 8.0 / sec (JPEG: 200); lossless compression RAW: 49; uncompressed RAW: 39)
About 5.7 frames / sec (JPEG: unlimited; lossless compression RAW: 62); uncompressed RAW: 43)
Expo: about 30 / [only for electronic shutters, 1.25 times crop] (half a time 20, up to 20 afterwards, the total number of 40)
Expo: about 20 / second [limited to electronic shutters, 1.25 times crop] (half a time, up to 20, up to 37 times, the total number of 57)
Expo: about 10 号 / Second [only for electronic shutters, 1.25 times crop] (half a day, up to 10 in total, up to 300 times, the total number of 310)
The X-T3 improved is not only connected. If you use old X-T2, X-H1, it will find that X-T3 focus speed increase is much more useful than connectivity speed. The X-T3 continues all the focus mode of X-T2, according to Fuji official data, its fastest AF speed is 0.06 seconds, the shooting interval is 0.17 seconds, the shutter release is 0.045 seconds, the startup time is 0.3 seconds, EVF refresh 100fps, Shooting racing and other high-speed regular movement goals have become extremely high, as long as it is not a human operation error, it can absolutely achieve 100% success rate, in case of complex goals such as trees, it will not recoose X-H1, X-T2's distraction problem, X-T3 is definitely the best AF camera in Fuji.
X-T3 shooting racing
At the same time, 425 phase differences in X-T3 can overwrite the entire screen (near 100% coverage), which is the highest in the unveiled camera, which can completely get rid of the focus range.
X-T3 focus is almost overwriting full screen
The phase difference of X-T3 has reached 2.16 megapixels, which can better implement the face, the eye recognition focus - the camera face recognition algorithm has always used simple and thick detection methods to identify the inverted triangle in the picture. Face, the more focus pixels, the higher the density, the smaller the face, the smaller the proportion of the picture, and identify the eye (two points in the inverted triangle), in the use of 29mm focus (XF16-55mmf2.8 r Lm WR) When shooting, X-T3 recognizes the farthest 5 meters away. However, on the low illumination AF, X-T3 can only achieve -3ev focus, inferior to a nearly nearly published Z6, EOS R, etc. No inverse camera.
Human face and eye identification
When faced with complex targets, X-T3 is no longer easily
X-T3 focus is significantly improved, and it can be quickly and focusing in large backlight. The picture is the processed RAW photo, and the character in JPG is nearly all.
X-T3 shot of black cat, rainy weather shooting, focus is not falling on black, X-T3 captures such goals will look loss
After the focus, after the continuous shooting performance is improved, it is naturally higher. The X-T3 is equipped with the three-way flipping liquid crystal screen of X-H1. It can be tilted 90 degrees, tilted down 45 degrees, and inclined to the right of 60 degrees; the EVF pixel is 3.69 million, the magnification is 0.75x, the refresh rate is 100 fps , The lateral delay is 0.005 seconds. However, in actual use, it still feels that the speed of viewing is not strong - not too high, but there is a similar drop-on-graded Carton, and Fuji still needs to upgrade the firmware.
X-T3 flip screen
The X-T3 skeleton delay is between 30,40ms, which is excellent in noise.
In X-T3, Fuji has also joined the new "sports viewer mode", which is a mode of use of 1.25X cut, 30fps high-speed electronic shutter, and then X-T3 will read the entire sensor. Scene, but mark the 1.25X cut range with a black box, which is convenient for users to view, but only 16.6 million pixels in the cut screen will only be recorded.
It is also BSI to defeat the BSI?
In recent years, BSI is considered an important technique that is considered to enhance the quality of CMOS sensor because it moves the logic circuit above the photodiode to the bottom, no logic circuit occurs, the photodiode can absorb more photons (quantum efficiency, and more sensitivity High), the picture quality is naturally better. But Sony is only halfwords when telling the story, BSI CIS noise (noise) is higher than the FSI type, must use other technologies to counteract BSI negative effects, perhaps this affects the high-sensitive quality of X-T3, no comprehensive transcendence product.
The above figure is the Different sensitivity contrast of X-T3 and X-T20, using XF16-55mmf2.8 r LM WR lens, RAW format shooting, ACR11 transcoding, and software is the default setting. The X-T20 is used by an FSI sensor. There is no difference between the image quality and X-T3 in low sensitivity. Under ISO 25600, X-T20 noise is less; the plot in ISO 51200 is reversed, X-T3 benefits More preferably quantum efficiency, better performance, bright screen than X-T20.
In the dynamic range of the reference sensitivity, the X-T3 is as low as ISO 160, but the actual effect is not dominated by X-T20. There is no complete transcendence of X-T20 in the X-T3 quality, one is Sony CIS itself, and the other is that the processor is not fully adapted to BSI-CSI, and the real reason can only leave time test.
4K practical
At the same time using the BSI-CSI sensor, X-T3 video has improved quality, it is the first to record 4K / 60P 4: 2: 0 10 bit video at the same time, HDMI output 4K / 60P 4: 2: 0 10 BIT video APS-C frame micro single camera; when shooting F-LOG + DR400% video, the lowest sensitivity has been lowered from ISO800 to ISO640. From the real shot, X-T3's 4K video resolution, the jelly effect is significantly improved, and it has achieved a practical level.
The above figure is X-T3, X-T20, GH5 three camera 4K30P comparison, X-T20 jelly is very serious, and the jelly effect of X-T3 is close to the GH5 level.

At 4k30p video resolution, X-T3 performance is similar to GH5, and the sharp traces are not obvious, and the actual resolution is better than GH5.
After upgrading the Ver 2.0 version, the X-T3 video function has also achieved a number of enhancements, as follows:
1. Support 4K HDR video recording in HLG format;
2. Implement F-Log recording when displaying analog film style video, when the X-T3 outputs a video to the monitor via HDMI, the monitor can display the film style, but the video is still recording with the F-Log style;
3. Allow a single video file to be greater than 4GB, when using 32GB of SD recording video, the video file will not be cut when the video file is more than 4GB;
4. Increase EVF / LCD color temperature display function;
5.DCI 4K / 4K 29.97P / 25P / 24P / 23.98P can use a slow shutter lower than frame rate;
6. Support all-i coding and H.264 400Mbps code rate;
7. Show an external power supply icon, compatible with the original AC-9VS and Anker PowerCore + 26800PD, PowerCore 20000PD.
The fastest and strongest APS-C
X-T3 and Fujian XF big three yuan
Fuji X-T3 is in the appearance, operates with X-T2, but benefits from the new BSI-CSI, X-Processor 4 processor, focus speed, accuracy, and continuous shooting speed, 4K The video jelly effect is sharply weakened, coupled with the strongest lens group in the APS-C box, has to say that it is the preferred product of the APS-C unveiled camera. If you corrections between X-T3, X-H1, we recommend that you sell X-H1 to make a scenery, still life, X-T3 is used to shoot sports, humanities, video.
Fuji Dragon XF is currently the strongest APS-C figures lens group, there is no opponent
