Sony a7III vs Fujifilm X-T4 or Full Frame vs APS-C

Thehybridshooter released his video review comparing the Sony a7III to the Fujifilm X-T4. He comes from a Sony background in this comparison and makes a few mistakes due to not being overly familiar with Fujifilm cameras, but it is a worth wild comparison and I would tend to agree with him about Sony being the pragmatic choice. If you just want to get the shot the Sony a7III is very hard to match or beat, but Fujifilm does have a feel to it kind of like Leica. You can read a summary of the above video below:

  • Both are great cameras
  • Sony a7III full-frame camera with great sensor, flawless AF, IBIS, best battery life, very compact
  • Fujifilm X-T4 more geared towards enthusiasts with a vintage look/feel with APS-C sensor, IBIS, class-leading video, engaging analog controls
  • Size and weight are similar with the Sony being a little smaller
  • Both are made of magnesium
  • Both have plastic IO doors that I do not like

  • Both cameras use BSI sensors but they are different sizes
  • X-T4 has more pixels 26 vs 24
  • a7III you can get good results with average lenses
  • X-T4 needs better lenses to get good looking photos since the pixel density is more
  • Full frame shallow depth of field look is easier on a7III
  • Sony a7III has an incredible dynamic range

  • X-T4 is about half a stop darker than a7III at same ISO
  • a7III is generally cleaner than X-T4
  • Fujifilm X-T4 ISO noise at 6,400 is about equal to a7III at 12,800
  • Sony a7III is acceptable at 12,800 and you can go higher depending on the scene
  • Fujifilm X-T4 shouldn’t go beyond 6,400
  • Similar color science with both
  • Both provide accurate color
  • Fujifilm has great simulations

  • a7III can only do 8-bit up to 100Mbps
  • Both cameras have good semi-flat profiles
  • X-T4 Eterna captures a lot of dynamic range with 10-bit files and this is currently his favorite way to record video
  • X-T4 Eterna is currently his favorite configuration for any camera
  • Sony’s flat profile is great too but is limited by 8-bit capture
  • X-T4 also has F-Log to work with
  • Sony’s automatic exposure changes smoothly for video
  • Fujifilm still has some issues with automatic exposure in video because it happens in steps
  • Fujifilm is the more advanced video camera thanks to the extra creative options
  • When it comes to handling Fujifilm has dedicated buttons for shutter/aperture/ISO
  • Sony has a more traditional setup with mode and exposure dials
  • Handling comes down to preference
  • Sony a7III has a larger grip that good to hold onto larger lenses
  • Fujifilm X-T4 doesn’t have the best grip, but it is pretty good
  • No complaints about Sony a7III button layout
  • Fujifilm has very good controls, but he doesn’t like the AF selector switch on the front, but likes the joystick on the back

  • Sony can shoot 10fps and AF-C
  • Sony E-mount has the best lens selection at the moment including 3rd party lenses
