Ever since I picked up the Fujifilm X100T, i've been a huge fan of Fujifilm mirrorless cameras for still photography. There's just something about the image quality and color that I favor over my Canon, Sony, and Panasonic Cameras. Now FujiFilm has introduced the X-T2 which is a serious Stills Camera but now has the added option for 4K Video recording.
Video recording on the Fujifilm X-T2 can be set to true 24p with an HDMI out at 4:2:2 with an F-LOG flat profile. Combined with the battery grip you'll have everything from a Microphone input to Headphone output. I don't think it will be a major video competitor to Sony or Panasonic but I can see this as an excellent camera for those who Primarily shoot stills and dabble in video every now and then.
