Fujifilm X-T2 video

As we've already covered, the X-T2 gains a mic socket and can capture up to around 10 minutes of 4K video footage. Add the optional 'Power Booster Grip' and the recording time extends to around 30 minutes (which we're taking to mean 29:59). Having three batteries significantly extends the recording duration between charges and the grip also adds a headphone socket for audio monitoring.

The X-T2 offers the best video yet from a Fujifilm camera and gains a mic input. Add the battery grip and it extends your maximum recording time and adds a headphone socket for audio monitoring.

The X-T2 creates its 4K video from a 1.17x crop of the sensor (so 1.725x, relative to full frame, if you're trying to think in terms of equivalent focal lengths). This is a 5120 x 2880 pixel region, meaning that it's oversampling by 1.33x along each axis. This is a long way short of the 2x oversampling needed for perfect UHD capture, but should mean less moiré and fewer artifacts than direct 1:1 sampling.

The 1080 video is taken from a slight crop of the scene, while the 4K comes from a more significant, 1.17x crop. This narrows the field of view somewhat, making it harder to find wide angle lenses to shoot with. This area is still oversampled, which should allow for detailed output.

But it's not just the addition of 4K that's new. Fujifilm has also added 'F-Log', a Log gamma profile. F-Log is only available over HDMI output (which features 4:2:2 chroma sub-sampling, so has more color information than the 4:2:0 signal captured internally). Fujifilm's logic appears to be that the more advanced user that understands how to use log gamma will want the best-possible quality by using an external recorder. Here's a demonstration of the benefits of log gamma.

In addition, the camera gains a mic socket and slightly more control over the autofocus. Not every problem has been solved, though: there are several obvious changes that would improve the camera's operation, particularly in terms of autofocus behavior.

At present the camera doesn't offer zebra highlight warnings, nor can you access the histogram while shooting. The ability to access manual white balance and adjust the highlight and shadow response has been added since we first saw the camera so we're hoping some of these missing features could appear in post-launch firmware updates.

Focus in video

The X-T2 gives a bit more control over video autofocus, with the main change being that you can choose between the existing 'Multi' mode (where the camera chooses what to focus on), and 'Single,' where you specify the focus target. This target can be moved as you record and the camera will refocus on your newly-chosen subject. AF-L is also available, to stop the camera refocusing when you don't want it to. This honors the toggle/hold setting specified for stills shooting mode but there’s no on-screen indication of when it’s active and you can't move the AF point while it's applied, so it's not nearly as useful as it could be.

Manual focus remains much the same as before: you can perform a single focus acquisition by hitting the AF-L button before you start shooting, or can press the rear command dial to access your choice of magnified live view and focus peaking. Once you start rolling, the ability to magnify the preview is lost but you do at least retain focus peaking, to help you judge manual focus pulls.

Remaining limitations:

With the camera's current firmware there are still several problems with the way the camera focuses in video. In AF-C mode, the camera attempts to refocus as soon as you move the joystick, rather than waiting until you've finished specifying a new subject, which risks the focus jumping to the background as you navigate between subjects. There's also no way to adjust the speed of focus, so don't expect subtle focus transitions.

Fujifilm's lenses with a focus scale offer a predictable manual focus response, making them easier to use than the ones that give a speed-sensitive response.

Manual focus also has its drawbacks: many of Fujifilm's lenses offer a speed-sensitive manual focus response, which makes it impossible to predict how far you have to move the camera's focus ring to hit your desired focus position (since the amount of focus movement is dictated by how fast you turn the focus ring). We'd much prefer that the manual focus ring responded in a linear fashion during movie recording. Finally, AF-S mode appears not to function at all: even if you've set a Fn button to be AF-On, the camera cannot be made to refocus during recording, meaning AF-S mode is essentially manual focus mode but without the distance scale.

Again, we're hoping some of these other shortcomings can be addressed with updated firmware.

Video quality

Our test scene only really allows you to judge detail capture and moiré. In this respect it looks competitive against most of the 4K-capable cameras we've tested so far, though a fraction behind those, like the Sony a6300, that derive their 4K from significantly oversampled footage. However, our real-world tests show that the X-T2 shows significantly less rolling shutter than the Sony, making it more useful in practice.

This is huge step forward for X-Trans cameras.

Sample video (shot with a beta camera)

We've put together a short sample video of the X-T2's 4K footage. All footage is 24p and shot with a shutter speed of 1/50th. Lens, ISO and focus methods used are indicated. Clips marked 'IS On' were shot hand-held using an OIS lens, all others were shot from a tripod.

F-Log sample video

This second video was shot using a production camera. Again, all footage is 4k/24p and shot at 1/50th shutter speed. Most of the clips were shot in F-Log captured using a Blackmagic Designs Video Assist 4K recorder and graded using Fujifilm's F-Log/F-Gamut to Wide Dynamic Range/BT.709 LUT (which you can download here).
