Only Fujifilm has eye detection during video autofocus.

Default settings

  • all cameras track really well

Subject moving out of frame

  1. Fujifilm X-T3 locks on first
  2. Canon EOSR second
  3. Sony and Nikon are slower but smoother [NOTE: on all these cameras you can set the video AF speed, for smoother transition]

Subject coming back in frame

  1. Fujifilm X-T3
  2. Nikon  Z7
  3. Sony A7III and Canon EOSR are tight

Face detection blocking

  1. Fujifilm X-T3
  2. Canon EOS R and Nikon Z7 second. But Canon suddenly detects a face where there is none, and focusses on it
  3. Sony A7III

Reactive face detection after blocking

  1. Fujifilm X-T3
  2. Nikon Z7
  3. Sony A7III
  4. Canon EOSR

Subject moving back

  1. Nikon Z7, Sony A7III and Canon EOSR
  2. Fujifilm X-T3 focused on the background a bit too early

Run towars camera

  1. All do a great job

Losing face detection

  1. TEST 1: Nikon Z7, Sony A7III and Canon EOSR lose face, but hold focus to the subject. X-T3 focusses on background
  2. TEST 2: Fuji X-T3, Nikon Z7, Sony A7III lose face, but hold focus to the subject. Canon EOSR focusses on background

Slow Motion (no Canon, since it has no AF)

  1. Fuji X-T3
  2. NikonZ7
  3. Sony A7III

Max notes that the AF shifting on X-T3 in slow motion is smooth when shifting forwards, less smooth when shifting backwards


In the video above, Max Yuryev compares the high ISO performance. His key findings:

ISO 1600

  • Sony A7III , Fujifilm X-T3 and Nikon Z7 are the cleanest
  • Sony has the brightest image, followed by Nikon, Canon, Fujifilm and last is the Blackmagic Pocket 4K
  • Most noise in Blackmagic Pocket 4K

ISO 3200

  • Sony looks good and Fujifilm X-T3 looks fairly good too

ISO 6400

  • Fujifilm X-T3 could be usuable, depending on your noise preferences
  • EOS R is not usable

ISO 12800

  • Sony A7III looks cleanest
  • Fujifilm X-T3 intraframe noise reduction switched on, and it helps

Intraframe noise reduction (available in everything but 4K 60p) reduces noise, but also details are reduced and it gives some luminance noise. Max says he would switch it on only at ISO 12800, unless you care ultimately about having zero noise also at lower ISO.
