It’s hard to fathom why Fujifilm
has shackled the X-T100’s 4K UHD video recording to a speed of 15 fps, unless it’s designed more for the high-speed still capture modes than for making movie clips. Who knows, but presumably it’s processor power related as is the case on the X-A5.
More usefully, Full HD footage can be recorded at 50, 25 or 24 fps with stereo sound and adjustable audio levels (with stereo level meters displayed in the LCD monitor. There’s a stereo audio input – albeit a 2.5 mm connection rather than the standard 3.5 mm – and the clip length, either 4K or 2K, is now 29 minutes and 59 seconds with automatic file partitioning at every 4.0 GB of data. Slow-mo video clips can be recorded at the HD resolution of 1280x720 pixels and down to one-quarter speed, but all settings are locked off during shooting and the maximum clip length is seven minutes. Timelapse sequences can be recorded in 4K UHD.
Streaming to the camera’s HDMI connector is available with both 4K and 2K video (8-bit, 4:2:2 colour), with the option of simultaneously recording 4K internally (8-bit, 4:2:0 colour) to a memory card and streaming. A handy ‘HDMI Rec Control’ sends start/stop commands to the external recorder when the shutter button is pressed.
The touch focus controls are particularly useful when shooting video and continuous AF is both smooth and reliable. The magnified image and focus peaking display are again provided to assist with manual focusing. For exposure control, both aperture and shutter speed can be manually selected, but the sensitivity range is reduced to ISO 400 to 6400.
The Full HD video performance is excellent, but 4K at 15 fps doesn’t really look particularly smooth - especially if anything is moving, either the subject or the camera. We noted with the X-T20 that it was unlikely to be selected primarily to shoot video, but it was still pretty capable here nonetheless. The same is true of the X-T100 except only in terms of its Full HD performance which means there are other better alternatives if you really want the 4K resolution without spending a fortune.
