The vast majority of people, who are going to get a Fujifilm GFX100, will get it for its photographic virtues.
However, the Fuji GFX100 is also the first medium format mirrorless camera that can fight an honorable battle with full frame and APS-C in the video department.
4K@30p, 4:2:0, 10 bit internal… not bad at all!
This is why I decided to highlight this review by Muse Storytelling, which focuses on the Fujifilm GFX100 for filmmakers. He says:
the whole demo video you see has been shot handheld with Fujifilm GFX100
10 bit gives you lots more colors over 8 bit and allows for more post processing
understanding Fujifilm film simulation allows you to create amazing images in camera
Velvia is great for scenes that look bright, happy and energetic
Classic Chrome more subtle and subdude look is great for interviews and moments with a serious or sad tone
external recorder for 4:2:2 10 bit image allows for simultaneous F-Log and film simulation recording
using film simulation you got to get it right in camera, less flexibility in post compared to F-Log
when using the LCD screen in bright daylight and shooting F-Log, it becomes a bit difficult to evaluate exposure and focus on the LCD screen, but it’s totally fine if you use film simulation
changing settings takes a bit longer than on dedicated film cameras like the RED camera they use, but you can set custom buttons to speed up your workflow
they say in most cases, for film you better use manual focus. But the AF system on Fujifilm GFX100 is great, and for interviews with people moving back and forth, the eye AF worked better than they could have done by manually focussing
sweet spot for exposure seems to be 1 stop over: gets all the shadows properly exposed and away from the toe of the curve
when using F-log or Eterna, the GFX100 holds highlights very well
he is impressed with image quality, handling and features for such a compact camera with such a massive sensor
they will use the GFX100 a lot more in future for their video work
