The Fujifilm X-T4 is a premium APS-C mirrorless camera. It offers very good image quality, impressive recording quality, and good image and video stabilization performance. Its autofocus performance for both photography and video is amazing, allowing you to clearly capture fast-moving objects and people without too much difficulty, although its photo autofocus can be a bit inconsistent. It's also exceptionally well-built and offers a wide range of photo and video configuration options. Unfortunately, it's quite heavy, making it a little tricky to carry from place to place.
The Fujifilm X-T4 is good for travel photography. It delivers very good image quality, even in darker environments. Its autofocus and in-body image stabilization features perform well overall, allowing you to quickly take clear pictures without the use of a tripod. Its 500-shot battery life should last you most of the day, while its metal body feels sturdy enough to take some drops and bumps, though it feels a little heavy.
The Fujifilm X-T4 is a very good choice for landscape photography. It takes sharp images out-of-the-box and doesn't exhibit much in the way of visual noise or graininess even when using high ISO settings in dimly-lit environments. Its kit lens also lets in quite a bit of light and doesn't exhibit much in the way of light falloff, so the corners of your image aren't noticeably darker than the middle. Its screen is also clear and legible even in direct sunlight.
The Fujifilm X-T4 is great for sports and wildlife photography. It can shoot at very high continuous speeds and has an effective autofocus system, allowing you to clearly capture brief moments. Its high maximum shutter speed should also help in this respect.
The Fujifilm X-T4 is excellent for vlogging. Its fully articulated screen lets you easily monitor what you're recording while its in-body and optical stabilization features keep videos stable, even when you're on the move. Its autofocus system should also do a fantastic job of tracking and maintaining focus on your face as you record, whether you're shooting in 4k or FHD.
The Fujifilm X-T4 is an excellent choice for studio video. Video quality is excellent, whether you're recording in 4k or FHD. Its continuous autofocus system easily keeps moving faces and objects in focus, although its object tracking can be a bit inconsistent. Unfortunately, it lacks a dedicated headphone jack, necessitating the use of a clunky USB-C adapter.
The Fujifilm X-T4 isn't designed for action video but offers decent performance. It isn't small enough to be mounted on a head rig, and it isn't waterproof, although we don't currently test for that. That said, it's sturdy enough to take minor drops and bumps and offers great video recording quality, regardless of whether you're filming in 4k or FHD. It can also record FHD video in 120 fps or 240 fps for the express purpose of generating slow-motion video, as playback is limited to 30 fps.
Update 05/31/2021: We previously indicated that the Fujifilm X-T4 didn't have any kind of weather-sealing or water resistance. However, it is in fact advertised to be weather-sealed, although this isn't something we currently test. The 'Water Resistance' field has been updated to reflect this.
Update 04/12/2021: Corrected input error in camera lens name.
Update 06/28/2021: We retested this camera's object tracking autofocus performance, updated the score accordingly, and reuploaded the new photos for the object tracking slideshow as reference. Overall, it performed very similarly to our original testing. However, it's important to note that the score is an average of three test runs and that the Fujifilm X-T4's autofocus in particular is somewhat inconsistent, ranging in between 60 and 78 percent success rates.
Update 02/04/2021: Following a retest, it was revealed that this camera has a recording light on the front of the camera, which can be configured to blink or stay lit while recording video. By default, however, it's set to "Off". The 'Recording Light' field has been set to 'Yes'.
Update 06/18/2021: We've amended the frame rates for this camera. The Fujifilm X-T4 is capable of recording FHD video in 120 fps and 240 fps, but it only allows for playback of this footage in slow motion at 30 fps. This feature is available in the 'Full HD High Speed Rec' menu (see here and here). Enabling it also incurs a crop.
The Fujifilm X-T4 comes in two color variants: 'Black' and 'Silver'. We tested the 'Black' variant with the FUJINON XF 18-55mm F/2.8-4 R lens, and you can see its label here. That said, we expect the 'Silver' variant to perform similarly overall.
It can also be purchased in either color scheme with the FUJINON XF 16-80mm f/4 R OIS WR lens or without a lens at all, but haven't tested the performance of these variants.
If someone comes across a differently-equipped variant of the Fujifilm X-T4, let us know in the discussions so we can update our review.
