DPRTV Fujifilm GFX100 Review for Video: No Dynamic Range/Low Light Benefits Over X-T3, but MF can Now do Pro Video Work


Fujifilm GFX100

While 99,99% of Fujifilm GFX100 owners will buy the camera for its photographic virtues (the new king of the DPReview lab tests), at the GFX100 launch Fujifilm also highlighted the video capabilities of the latest medium format GFX camera.

And sure, on paper, also the Fujifilm GFX100 video specs are impressive (10 bit internal, 400 mbps, no crop 4K, IBIS etc).

But how does it work in real life for video?

DPReview TV has tested the Fujifilm GFX100 for videos, and here are their findings:

  • 10 bit internal gives lots of flexibility
  • no high-speed camera (no 4K/60p, no 1080/120), because it must scan a very big sensor and this takes a lot of time
  • Jordan is fairly impressed by IBIS and continous tracking in video
  • IBIS is very smooth, but occasionally there can be a quick shift into one direction and can be a bit jarring when you do a smooth pan
  • AF tracking does a great job in keeping up, especially at smaller apertures
  • AF tracking using the GF11o at f/2, it will smoothly shift between larger steps and it can be a little bit jarring
  • AF tracking is better stopped down, but overall it does a pretty good job
  • ETERNA looks great for video, and gives still a bit of room in post
  • F-LOG a lot more flexibility in post
  • You can get a standard LUT from Fujiiflm or the Eterna LUT, so you emulate the Eterna look with more dynamic range
  • HLG gives about the same dynamic range of F-LOG. Good if you want to do a little less work in post and don’t want to use a LUT
  • in 4K, the Fujifilm GFX100 uses the entire horizontal width of the sensor, and of course there is crop on top and bottom for wide screen, hence you get a very similar field of view on your lenses to when you are shooting stills
  • pixel binning and line skipping are used to produce 4K video
  • there is some rolling shutter, but not nearly as bad as in stills
  • low light performance is very good on the GFX100, but some APS-C and FF cameras are also outstanding in that
  • Jordan would not get the GFX100 specifically for low light performance, also because MF lenses tend to be slower than APS-C and FF lenses
  • dynamic range on GFX100 in video is identical to the dynamic range of X-T3
  • you can absolutely do video job for clients with the GFX100
  • there is no benefit to the big sensor in video the way that you see them in stills
  • Dynamic range is the same of X-T3, low light is not much better, the lenses are bigger, and it costs 5 times the X-T3, which shoots 4K/60p and 1080/120
  • you should not buy the GFX100 for video, but it is cool to know, that if you buy one of the best photo cameras ever made, you still get video features you can use for your creative jobs
