Another big change is a new mechanical shutter that Fujifilm calls “the fastest and most robust in the history of the X Series.” It’ll let you shoot bursts at up to 15 fps with the mechanical shutter with full autofocus and auto exposure (or 20 fps with the electronic shutter), while lasting for up to 300,000 actuations. That kind of speed and shutter life is pretty incredible for a camera in this price range — by comparison, Canon’s 1DX Mark III can shoot at 16 fps with the mechanical shutter, but it costs $6,500.

The autofocus system is a lot faster, down to about .02 seconds, nearly matching what Sony can do. Tracking and face/eye detection performance has also seriously improved, with Fujifilm claiming the X-T4 has a success rate double that of the X-T3.

The rear display not only has more resolution (1.62 million pixels compared to 1.1 million on the X-T3), but it finally flips around fully so that you can see yourself for selfies or vlogging. There’s also an updated electronic viewfinder (EVF) if you prefer to shoot that way, but it’s got the same 3.69 million pixel resolution and 100 fps refresh rate as before.

You’ll be able to shoot for longer, too, thanks to a much bigger 2,200 mAh battery (compared to 1,260 mAh on the X-T3) that can shoot 600 shots on a charge, compared to 390 before. Despite all the new additions, the X-T4 weighs has only gotten a few millimeters deeper, and weighs just 607 grams with a battery and memory card, compared to 526 grams for the X-T3.

The X-T4 doesn’t have 6K video as was rumored, but it can still shoot 4K at 60 fps and now handles 1080p at an 240 fps — double what the X-T3 can do. As before, 10-bit video can be recorded internally and externally with F-Log mode to maximize dynamic range. However, Fujfilm has introduced a View Assist function that boosts contrast and saturation for shot previews when using F-Log. Continuous autofocus subject tracking now works in lower lighting conditions (down to -6EV).

Video can be recorded to both UHS II SD cards at the same time for a backup, while the microphone setting can be switched between input and line levels. The bigger battery, image stabilization and fully-articulating screen will obviously also be a big help for cinematographers and vloggers, too.

The launch of the X-T4 makes me wonder about the future of the X-H1 lineup, as the new model is just as capable while being more stylish and compact. What’s more certain is that Fujifilm is now well ahead of Sony in the APS-C category, as this model roundly beats Sony’s APS-C flagship A6600 in terms of specifications (albeit at a higher price).

The X-T4 will go on sale in spring of 2020 for $1,700, which is $200 more than the X-T3 cost at launch. Given the extra features, though, it looks to be worth the price — we’ll know more once we do a full review.

You’ll be able to shoot at those speeds for quite a while, as the 1D X Mark III will use CFexpress cards (with speeds up to 1,600 MB/s) and a buffer five times the size of the 1D X Mark II. As a reminder, that model let you shoot up to 170 RAW photos without stopping, so 1D X Mark III owners might be able to shoot 16fps or 20fps bursts for well over 30 seconds at a time. That kind of shooting burns through batteries quickly, but Canon said the 1D X III would eke better life out of the same LP-E19 battery used before.

Along with JPEG and RAW files, users will get a new type of format called 10-bit HEIF (high efficiency image file), with more dynamic range and a wider color palette than JPEG. It’s an option that’s much more compact than RAW, but easier to edit than JPEG. On the connectivity side, it comes with WiFi, Bluetooth LE, GPS, a built-in ethernet connection and an optional wireless transmitter.

Canon also revealed that the 1D X Mark III will be the most video-capable EOS camera it has ever built, with 10-bit 4:2:2 footage at up to 4K 60p, with internal Canon Log recording. It didn’t say whether 4K video would use the full width of the sensor and be supersampled, but the last model had a small 1.3 times crop factor.

As a pro model, it will have “phenomenal” weather-sealing and a very durable magnesium alloy body. Canon didn’t reveal the sensor resolution, price and other important facts, as it’s saving those for the official launch. As a reminder, though, the last model had a 20.2-megapixel sensor and $6,000 price tag.

In other Canon news, the company unveiled two new lenses that will complete its “holy trinity” full-frame EOS R RF-mount lineup. The $2,700 RF 70-200mm F2.8L IS USM is designed for sports, wildlife and event photography, but it’s 27 percent shorter and 28 percent lighter than the EF version. The other model is the $3,000 RF 85mm f/1.2L USM DS. It features a new Canon lens coating called Defocus Smoothing — a vapor-deposited coating on a lens element that improves the look of bokeh. Both of these models showcase the strengths (and high prices) of Canon’s RF mount system.
