Fujifilm X-T4  Camera Review

The Fujifilm X-T4 is fairly portable, especially compared to most full-frame hybrid cameras. It has a small grip that keeps its size down, though it's a bit on the heavier side. Still, for most shooters, it won't cause too much fatigue.

The build quality here is excellent. The camera is made of sturdy magnesium alloy and feels very solidly built, with weather-sealing to keep out dust and moisture. The buttons and dials all feel of high quality, and the dials aren't loose or easy to change by accident. The screen mechanism also feels very sturdy. While the SD card slots and battery compartment are covered with hinged doors, the inputs on the side of the camera only have rubber flaps.

The camera's ergonomics are decent. The camera is large enough for most hand sizes, and the textured grip around the body feels secure, but it's not the deepest hand grip, so it can be a bit slippery, especially if you have larger hands. For a larger grip, you'll have to look to more pro-oriented hybrid models like the Fujifilm X-H2 or Fujifilm X-H2S. Like most Fujifilm cameras, the X-T4 has dedicated physical controls for ISO, shutter speed, and exposure compensation, making it easy to adjust exposure settings without diving into the menu. That said, the eyecup around the viewfinder is a bit stiff, and the shoulder strap attachment points are somewhat in the way. 

The EVF is quite large, with a relatively high resolution. While some newer cameras have even higher resolutions, like the Fujifilm X-H2S, you'll still have a sharp, clear view here.

The camera has a fully articulated screen. It's quite bright for use in sunnier conditions, and it has a relatively high resolution. It's not quite as high as the screen on the Fujifilm X-T5, which also features a 3-way tilting design, but it's sharp enough. Touch functions are limited to selecting focus points or changing settings while recording videos.

The menu is fairly simple and easy to navigate, though some settings are buried in submenus and harder to find. Thankfully, the camera includes visual graphics for certain settings and functions, though there's no additional info button or 'guide' mode. Fujifilm also uses its own terminology for certain settings, like 'photometry' for metering settings, which can take some getting used to. But overall, it's pretty intuitive.

The Fujifilm X100V is also compatible with Fujifilm's XApp, which Fujifilm claims to offer smoother wireless connectivity between X series cameras and smartphones than the older Fujifilm Camera Connect app. You can use it to transfer files or control the camera remotely.

The Fujifilm X-T4 uses a fourth-generation 26 MP X-Trans sensor and the X-Processor 4. It has a fairly wide ISO range and a backside-illuminated design that's intended to improve its light-gathering ability.

The Fujifilm X-T4 has a great battery life. It's CIPA-rated for 500 shots on a full charge, which is great, especially among mirrorless cameras. However, these ratings don't necessarily align with real-world numbers, so you're mileage will vary depending on how you use your camera. 

Its video battery life is decent, lasting for about an hour and a half of 4k video recording. That's fairly middle of the road, but if you need to extend the battery life, you can use an external power source.

The Fujifilm X-T4 can shoot at a quick max burst rate. Its mechanical burst rate maxes out at approximately 12 fps, which is excellent, and with the electronic shutter, it can shoot at up to 20 fps. While newer models, like the Fujifilm X-T5, have improved further, the X-T4 is still great for continuous shooting. 

Unfortunately, however, the photo buffer fills up quite quickly when shooting in RAW format, and once full, it takes a long time to empty, which can interrupt your shooting. In JPEG, the buffer is notably bigger, but will still fill up after about 160-170 frames.

The camera uses a hybrid autofocus system. It includes a few different area modes and a 'Tracking' mode in AF-C that follows any subject beneath your focus point. In addition, there's a Face/Eye detection system that can automatically detect and track human faces or eyes. Overall, however, the tracking system is inconsistent. With faster or more erratic subjects, it can struggle to keep up, resulting in a disappointing keeper rate. For a Fujifilm camera with improved AF tracking, check out the Fujifilm X-H2S.

If you disable tracking and stick to a center focus point, the camera has very little trouble staying with the subject. As long as you can keep your subject under the focus point, you shouldn't have any issues with autofocus.

We tested AF-C with the FUJINON XF 18-55mm F2.8-4 R OIS.

The camera features in-body image stabilization, and it can also be paired with optically stabilized lenses, like the FUJINON XF 18-55mm F2.8-4 R OIS, with which we tested image stabilization. Using both IBIS and OIS, the camera can capture clear handheld images at very slow shutter speeds. However, stabilization performance can vary with different factors, including but not limited to what lens you use, what focal length you shoot at, and how steady your hands are.

The Fujifilm X-T4 has good dynamic range. It can't capture as wide a range of detail in high-contrast scenes as full-frame cameras like the Sony α7C, and it performs worse here than the newer Fujifilm X-T5. You'll see some highlight clipping or shadow noise in very high dynamic range scenes, but it's solid overall.

The Fujifilm X-T4 has a relatively high resolution sensor, so it can capture a lot of fine detail. You'll have a bit of room to crop your images but not as much as you would with a higher-resolution sensor camera like the Fujifilm X-T5.

The camera has decent noise handling in low light. Noise is a bit more apparent than on full-frame competitors, but for an APS-C sensor, it performs well.

The Fujifilm X-T4 has some great video features for its class. It supports Log shooting in F-Log, and it can output 10-bit 4:2:2 video to a compatible external recorder to get more dynamic range and have more leeway in post. Still, compared to newer models, it's missing certain features, like higher-resolution recording and internal 4:2:2 subsampling.

The camera can capture 4k video at up to 60 fps with just a slight crop at the max frame rate. That's great if you want to record high-speed action or slow your footage down somewhat, though it doesn't support higher frame rates. If you'd like a camera that can record 4k at 60 fps without a crop, check out the Canon EOS R7.

The camera's internal recording capability is good overall, though it has some limitations, especially compared to newer cameras. For one, there's a 30-minute cap on recording, and while it does support internal 10-bit capture, it's limited to 4:2:0 chroma sampling internally. Overall, that's not bad, unless you're shooting footage that requires more keying and work in post. If you need a camera that can do 4:2:2 subsampling internally, consider the Panasonic LUMIX GH5s. The X-T4 can also overheat with prolonged recording sessions, though it isn't too bad overall.

The camera's autofocus performs incredibly well in video. It's very consistent at tracking moving human subjects, even when they move in and out of frame. Its manual object tracking performance is just as good, with smooth and responsive focus transitions.

The camera has excellent 4k video quality. It's especially good in more controlled lighting, with sharp details and colors that pop using the default film simulation profile. Videos look great in low light too, without too much noise.

The camera has noticeable rolling shutter distortion when panning the camera. It's especially pronounced with very quick camera movements.

The Fujifilm X-T4 can record FHD video at up to 60 fps in standard recording. It also has a high speed recording mode that captures 1080p footage at either 120 fps or 240 fps, with slow motion playback at 30 fps. This feature doesn't record any audio and incurs a crop.

The camera's internal recording capability is good overall, though it has some limitations, especially compared to newer cameras. For one, there's a 30-minute cap on recording, and while it does support internal 10-bit capture, it's limited to 4:2:0 chroma sampling internally. Overall, that's not bad unless you're shooting footage that requires more keying and work in post.

The camera's autofocus performs incredibly well in video. It's very consistent at tracking moving human subjects, even when they move in and out of frame. Its manual object tracking performance is just as good, with smooth and responsive focus transitions.

The video quality is great in FHD. Video is reasonably sharp and detailed, and the colors pop out of camera. It performs well in low light, with a bit of noticeable noise, but overall, it's fairly clean.

Rolling shutter performance is better in 1080p. While you'll still see some skewing and wobbling with quick camera movements, it's less pronounced than in 4k.

The Fujifilm X-T4 has excellent dynamic range in video. It captures a very wide total dynamic range, with a clean background floor. It's usable dynamic range, however, is more limited, though you can still capture a max of about 12 stops of usable dynamic range. That makes it well-suited to recording in trickier lighting conditions, with plenty of detail retained in the shadows and highlights.

Tested settings:

• Resolution: 4k
• Frame Rate: 30 fps
• Log Format: F-Log

The camera has a greater allocation of dynamic range in the shadows than the highlights. It preserves detail especially well at lower ISO settings.

Tested settings:

• Resolution: 4k
• Frame Rate: 30 fps
• Log Format: F-Log

The Fujifilm X-T4 has dual SD card slots, both rated for UHS-II cards. They're well placed on the side of the camera, making it easy to switch out cards when using a tripod.

The camera uses a USB-C port for charging, power delivery, and file transfer. It also features a Micro (Type D) HDMI port and includes a mic input. Unfortunately, there's no built-in headphone jack, but the camera does include a 3.5mm-to-USB-C adapter in the box. Still, that means if you need to power the camera externally, you'll have to choose between power delivery and in-camera audio monitoring.
