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 great 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 screen is also clear and legible even in direct sunlight.
The Fujifilm X-T4 is very good 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 great 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 great 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.
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.
The Fujifilm X-T4 is better overall than the Fujifilm X-T30 II, though they both use the same sensor, so image quality is roughly on par between them. If you prefer a more robust camera with weather-sealing, a bigger high-resolution viewfinder, and a fully articulated screen, get the X-T4. If you're looking for something smaller and easier to carry around, the X-T30 II is still a great option. However, the X-T4 also has better internal video recording capability, so it's a better option for video work.
The Sony α7 IV and the Fujifilm X-T4 are both great hybrid photo/video cameras, but they use different-sized sensors. Because the Fujifilm uses an APS-C sensor, it's more portable than the Sony, but both cameras are well-built, weather-sealed, and have fully articulated touchscreens. The Fuji also has a faster max burst rate and better overall stabilization. On the other hand, the Sony's full-frame sensor gives it better low-light and high-ISO performance and better dynamic range. When it comes to video, both cameras can shoot 4k / 60 fps, although the Sony incurs a larger crop at this frame rate, and they can both record 10-bit 4:2:2 video internally. While the higher-resolution full-frame sensor on the Sony offers some advantages over the Fujifilm, the Fuji is still competitive, especially if you prefer a more compact form factor.
The Fujifilm X-T4 and the Olympus OM-D E-M1 Mark III are both great all-around cameras, but the Fujifilm has a slight edge thanks to its larger sensor, slightly more compact design, and more advanced video features. Though the Fujifilm isn't quite as comfortable to shoot with, its APS-C sensor has better noise handling and dynamic range than the smaller Micro Four Thirds sensor of the Olympus. It also has a better battery life and higher-resolution EVF. That said, the Olympus has a faster max burst rate and extra features like a high-resolution photo mode and digital ND filters that still make it an appealing option for photography. However, when it comes to video, the Fujifilm offers better internal recording, higher bit rates, and 4k / 60 fps recording.
The Fujifilm X-T4 and the OM SYSTEM OM-1 perform similarly overall, though they use different-sized sensors. Both cameras have highly effective IBIS systems, decent if somewhat inconsistent autofocus systems, and similar video specs. That said, the Fujifilm is a bit more portable, with dedicated exposure dials that give it a slightly more hands-on shooting experience. The OM SYSTEM, on the other hand, offers faster electronic burst shooting and more computational photography modes, along with generally smaller lenses.
The PENTAX K-3 Mark III and the Fujifilm X-T4 are both premium APS-C cameras, but they use different technologies with different advantages and disadvantages. The PENTAX is a DSLR, so it's heavier and bulkier, but it has an optical viewfinder and longer battery life. The Fujifilm, on the other hand, is a mirrorless camera, allowing for a much more portable body. It also performs significantly better when it comes to video features and autofocus tracking.
If you're looking for a camera that can do 4:2:2 subsampling internally, consider the Panasonic LUMIX GH5s.
