Fujifilm X-T4 mirrorless camera can crank out 15 frames per second
Fujifilm's X-T series has just raised the bar with the release of the fourth-gen model, the X-T4. So what's new in this forthcoming mirrorless camera?
First thing's first: the X-T4 features the same sensor and processor as the earlier X-T3 - that's a 26-megapixel X-Trans CMOS IV, if you're wondering - meaning the image quality potential between the two cameras is one and the same.
Where the X-T4 steps things up is in a few main areas.
First, it's got a new in-body stabilisation system, said to support for up to 6.5 stops, paired with a new shutter system that's capable of shooting up to 15 frames per second (15fps).
Second, there's a new battery system. The cells are far more capacious than the outgoing model, which means they're longer-lasting, but also larger as a result - therefore the X-T4 is about 10 per cent bigger and heavier than the X-T3.
Third up, the video mode - or movie mode, if you prefer - has its own dedicated switch to activate. This takes the camera into movie-only functionality, with a dedicated silent menu if you need to change settings. Plus the Full HD (1080p) mode can now shoot at 240fps for one eigth slow-mo (the 4K mode remains at 60fps, if you want Ultra-HD instead).
That's the X-T4 in summary. If you want to know more about the camera then take a look at our full hands-on preview of the camera, which we saw ahead of its official unveil.

What should you consider when buying an action camera?
From holiday snaps to your baby’s first steps, your smartphone camera has you covered for everyday moments in life. But when it comes to breathtaking action and adventure, a smartphone camera just can’t keep up — enter the modern-day action camera.
Action cameras offer you an entirely new way to film your adventures, featuring durable designs, waterproof casings, and state-of-the-art imaging capabilities.
If you’re in the market for an action camera, hold on tight and launch yourself into a world of adventure with this article. We will discuss the action camera features you should consider and reveal some of the best options on the market in 2020.
Durability: Whatever the weather
Durability is one of the most important features to consider, as it will determine how well your action camera can keep up in any given shooting environment. The best action cameras on the market can withstand extreme temperatures, dirt, a dive into the ocean, or even being dropped. Waterproofing is a good feature to look out for if you wish to dive deeper for more content. DJI, GoPro, Sony, and other companies offer action cameras that are waterproof, shockproof, and resistant to extreme environments.
Stabilisation: Hollywood shots
Stabilisation has become a huge factor to consider when choosing an action camera. Whether your skiing down a mountain, running along a track, mountain biking, or recording other dynamic shots, stabilized video makes a world of difference to your footage. Most modern-day cameras come equipped with their own internal stabilization, letting you focus more on the action rather than worrying about the shot. When it comes to action camera stabilization systems, key contenders re DJI’s RockSteady, which made its debut with Osmo Action, and GoPro’s HyperSmooth, which was introduced with the GoPro Hero 7. We recommend checking out the stabilization availability of different action cameras for different resolution combinations.
Videos: 4K and beyond
The main function of an action camera is to capture dynamic, high-quality videos in any environment. Most action cameras in 2020 can now shoot both HD and 4K videos, which means you should pay attention to things like HDR support, 60fps frame rates, slow motion, and integrated shooting modes. A great example of this is Osmo Action, which features HDR video, 240fps slow-motion mode at either 1080p or 720p, and timelapses in 1080p, 2.7K, and 4K.
Images: Simple shooting
In addition to videos, an action camera should be able to take exceptional still images. A larger lens captures more light, which improves your images and video quality. Look for action cameras that offer intelligent image processing. The Sony RX0 II has one of the largest camera sensors of any action camera and offers a range of image control and dynamic range modes.
Lens: Wide-angle views
Action cameras are known for their point-of-view lenses, which use a very wide-angle view to capture yourself and all of your surroundings in one frame. Most action cameras on the market can produce a wide-angle shot that is perfect for capturing all the action in one shot.
Screens: Perfect selfie shots
An action camera screen monitor is an important feature to consider when you are purchasing your equipment. A screen helps you see what the action camera is recording, review your footage, and change settings easily. The DJI Osmo Action triumphs in this category, featuring a 2.25-inch touchscreen on the back and a vivid 1.4-inch selfie screen at the front.
Voice control: Focus on the action
Every second counts when you are undertaking extreme sports activities. Voice control is a fantastic feature that lets you control your action camera while focusing on the moment at hand. This clever feature gives you control over recording, taking a photo, turning the device on and off, and more.
Also consider
There are lots of other action camera features you should consider. Wi-Fi or Bluetooth connectivity makes it easier to transfer your images and videos to your phone or laptop. No matter how impressive the hardware is, software stability should always be considered when purchasing your action camera. A dedicated app lets you edit your footage, download files, change the camera settings, and more. Battery life is also an essential thing to consider; most modern action cameras can record for over an hour on a fully charged battery.
Some action cameras to consider...
Now that we’ve gone through some important action camera features, it’s time to check out some of the best action cameras in 2020. Here are five of our favourites!
DJI Osmo Action
To kick off our list of recommended action cameras, we will start with an action camera that has changed the game.

Next on our list is GoPro’s new successor to the Hero 7 Black — introducing the GoPro Hero 8 Black. Built on the success from previous models, this new model features a slimmer design, a foldable built-in mount, a better microphone, and updated EIS stabilization.
GoPro introduced HyperSmooth 2.0 with the Hero 8 Black, offering stabilization functionality across all resolutions and frame rates. Included with this update are three modes of stabilization that crop the frame at different levels to counter camera shakes. HyperSmooth 2.0 can also be applied to slow-motion footage shot at 120fps and 240fps.
In addition to these updates, a narrow lens perspective lets you shoot close-up footage, 2.7K and 4K video modes now support bitrates up to 100 Mbps, and social media live streams can be broadcasted at 1080p.
The Hero 8 Black also comes with built-in foldable hinges that allow it to be attached to other accessories like a tripod. This convenient feature removes the need for an additional frame mount for accessories and gives you easier access to the battery and memory card.
Insta 360 One X
This innovative action camera brings some impressive features to the market. The Insta360 One X offers sharp footage at 5.7K 30fps, 4K 50fps, and 3K 100fps. An HDR mode ensures your footage maintains excellent details in different types of lighting conditions. The Insta360 One X also features its own form of electronic stabilization, named FlowState, which provides stability for all of your action shots.
When it comes to exciting features, Insta360 One X brings heaps of action to the table. Snap the action camera into the Drifter accessory to create stunning slow-motion shots with ingenious angles. The accessory features an aerodynamic body and a shock-resistant frame, letting your creativity take flight. Another useful accessory is the invisible selfie stick that produces great selfies without appearing in the footage itself.
Insta360 One X also impresses with various shooting modes. TimeShift gives you control over your perspective by using slow motion and stabilized hyperlapses. These features are all combined with the One X app for simple, cinematic editing.

Fujifilm X-T4 initial review: Mirrorless boss brings bolder feature set
The long-standing Fujifilm X-T series has in the past set the benchmark for being the mirrorless camera to beat all others. Indeed, the X-T3 won Best Camera in the 2019 Pocket-lint Awards.
Now there's a new kid in town: the Fujifilm X-T4. But does this latest camera add enough extra to warrant its purchase? We got to play with a pre-production camera ahead of its official announcement, so here's what you can expect.
X-T4 vs X-T3: What's new?
- X-T4 adds:
- New in-body stabilisation unit (IBIS)
- New shutter unit (15fps mechanical)
- Dedicated movie mode
- New battery system
At a glance the X-T4 looks a lot like its X-T3 younger brother. But there are some clear differences. The newer camera is a little larger and heavier, on account of a new battery system that's designed to last longer.
Some weight has been shed elsewhere, to avoid it getting altogether too heavy, by introducing a newer, smaller in-body stabilisation system, which is said to be capable up to 6.5 stops (up from the 5 stops of the X-H1, where in-body was first introduced by Fujifilm).
In tandem with the stabilisation system is a new shutter mechanism, capable of up to 15 frames per second (15fps) burst shooting. It's also tested to 300,000 shutter cycles, doubling the durability over the X-T3.
Other little tweaks should make a big difference for movie users: a dedicated movie mode, with its own Q Menu on-screen settings (useful for silent adjustment), and even a removable SD card door, should you be shooting from a rig. The rear LCD screen is also a little higher in resolution than before (1.62m-dot compared to 1.04m-dot).
Elsewhere the specification is built around the same core as the X-T3: this means the X-T4 has the same sensor and processor combination, same on-sensor autofocus capabilities (albeit with some algorithm tweaks to improve tracking and face/eye-detection). So if you're looking for higher resolution or advances iin quality in that area, then the two cameras don't differ.
How does the X-T4 perform?
- New magnesium alloy body footprint: 134.6mm x 92.8mm x 63.8mm / 607g
- 3-inch tri-adjustable LCD touchscreen, 1.62m-dot resolution
- 0.5-inch, 3.69m-dot OLED electronic viewfinder
- Improved autofocus algorithm
- 425 selectable AF areas
The X-T4 is made primarily from magnesium alloy, which gives it a robust feeling in the hand. It's also weather-resistant, so paired with a suitable lens you needn't worry about splashes and rain.
The X-T4 is larger than the X-T3 given its new battery system, but that extra little bit of bulk and 10 per cent weight increase is worth it on account of longevity. The new battery is 2,200mAh in capacity, which is a big increase over the 1,260mAh of the X-T3's cell. Fujifilm says you can expect over 500 shots per charge as a result.
There's also a new vertical grip, which can house two additional batteries, and comes with a dedicated switch to flick between normal, boost and economy performance modes. The X-T3 grip won't fit onto the X-T4 due to the new battery system and different camera footprint.
Recharging takes place via USB-C, much like an Android phone, but you'll need to use a 15W charger at the wall for the fastest possible recharge times. It'll take about three hours to recharge the one cell, which isn't especially quick, but use a low power USB port and it'll take three or four times longer than that!
The X-T4 has the now staple rear LCD and OLED viewfinder setup. The vari-angle touchscreen is easy to use, benefits from that added resolution, while the X-T4's OLED finder is the exact same as found in the X-T3. That means it's got all the resolution you'll need, complete with a high refresh-rate, deep contrast, and a massive 0.75x equivalent magnification size - which makes for a formidable finder scale to this eye.
If you're familiar with the X-T3's autofocus - which we found did a great job at the Goodwood Revival motor show - then it's much the same with the X-T4. The camera uses a massive 2.16-million phase-detection pixels embedded across its sensor's surface, designed to cover the full width from edge to edge. That means you can focus anywhere in the field of view, as far vertically or horizontally as you wish, and still acquire the same focus ability as you would in the centre.
The autofocus system is pared down to 425 areas maximum, which can be further reduced to simplify operation as you wish. The AF point can be adjusted between a variety of point sizes, too, by using the rear thumbwheel. There's still no Panasonic-style Pinpoint mode, however, which we always miss when using other brands' mirrorless cameras.
Fujifilm claims the X-T4 has tweaked the tracking and face/eye-detection for the better, but we've not been able to shoot in suitable scenarios as yet to discern any major difference.
With a decent lens on the front and the X-T4 is a formidable shooting machine (yes, we know, it's pictured here with a basic 18-55mm kit lens, but Fujifilm offers plenty of better glass). From its 15fps burst, to the various custom settings (much like you'll find in a pro DSLR, in a scenario-appropriate format), mirrorless system cameras don't really get any better than this.
What's the X-T4's image quality like?
- 26-megapixel X-Trans CMOS 4 sensor
- ISO 160-12,800 (80-51,200 ext)
- New: Eterna Beach Bypass filter
Just like the X-T3, the X-T4 features Fujifilm's fourth-generation X-Trans CMOS sensor. This sensor is backside illuminated, with the copper wiring placement beneath the photo diodes in the sensor, in order to create a cleaner signal path.
That all worked a treat in the X-T3 and it's much the same here: image quality is exemplary. Although, as we always say, a lot of that comes down to the lens on the front of the camera. And Fujifilm's range of optics means there's something for more or less every situation. The 18-55mm we've used for this preview is fine, but not the hottest ticket, we've found the 40-150mm f/2.8 and 50mm f/2.0 to impress us much more - especially those wider aperture lenses.
We've shot with the X-T4 in and around Fujifilm's House of Photography in central London, where there's a variety of light sources and situations. That's given a broad scope to test out the baseline ISO 160 sensitivity, right through to the higher ISO 12,800 setting when shooting a vase of flowers in the dim-lit (off public limits) basement at the property.
Low-light will show some grain, of course, but it's not overwhelming by any measure and even the four-figure ISO settings are really clean looking. But daylight is where things really shine, those lower settings giving real clarity.
We've always praised Fujifilm for its image quality prowess, a trend that the X-T4 continues. No, it's not more resolute or more advanced than the X-T3, which some will see as a downer, but as that camera was already accomplished you're really looking to buy this newer model for its better battery, faster burst rate and improved image stabilisation (although it's a marginal improvement in that regard).
The X-T4's new video capabilities
- Dedicated movie mode, via physical switch dial
- Dedicated Q Menu with silent mode selection
- 4K 60fps maximum, 1080p 240fps slow-mo
- Can fix crop to 1.29x for all modes
The X-T4 has also clearly been engineered with the videographer in mind. Not only on account of the better battery and removable SD card door, but also the dedicated movie mode, which is activated via a physical switch beneath the shutter speed dial atop the camera.
Moving this switch over to 'Movie' means you get a dedicated Q Menu, which is accessible during shooting and means silent adjustment of modes is possible using the touchscreen. The physical dials will also work, but if you want to avoid the physical motion and clicking sounds then this is one way around it.
The frame-rate possibility has also increased, with Full HD (1080p) now available at up to 240fps. Some would call that slow-motion to one eighth the speed of a normal 30fps capture. The X-T4 is also 4K capable, offering 60fps in this Ultra-HD mode (just like the X-T3).
All this adds up to a much more accomplished and movie-focused device, in an attempt to outsmart the Panasonic and Sony options on the market.
