Fujifilm to Release Free Firmware Update – Upgrading the AF performance of the FUJIFILM X-T3


To our customers

FUJIFILM Corporation (President: Kenji Sukeno) plans to release free firmware update for the “FUJIFILM X-T3” (X-T3) on October 28, 2020.

The update will improve the autofocusing performance of the X-T3 to the same level as the “FUJIFILM X-T4” (X-T4).  This firmware will boost the AF speed, the camera’s AF tracking performance and the Face / Eye AF. In addition, the size of the AF area can now be adjusted during video recording. The update will bring new life to the X-T3, adding greater speed to make a great camera even better.

Main updated features:

Due to be released on October 28, 2020Firmware version: FUJIFILM X-T3(Ver. 4.0)

1. Faster autofocus performance

The fastest AF speed has been improved from 0.06 seconds to 0.02 seconds, equivalent to the performance of the X-T4. The algorithm for predicting subject movements has also been updated which means the expected ‘hit rate’ is now 90% or more , making it even more likely that users will capture that precious moving photo moment.

  • AF tracking performance has been doubled*. Press the shutter button halfway down when a subject is in  the focus area to maintain focus on the subject with a higher level of accuracy.
  • The Face Tracking / Eye AF performance has also been upgraded. The algorithm has been re-written to double* the tracking performance of the Eye AF in continuous shooting modes. The camera can attain focus on a face or eyes quicker and more accurately even when shooting portraits that involve some movement.
  • The update also allows the camera AF to work in low light levels down to -7EV**, facilitating fast and highly-accurate phase detection AF even in near darkness.
  • The new firmware adds the “Focus Limiter” function which gives a pre-define specific focus range.

  • Photo ratings can now be read by third-party software, allowing users to find their favorite pictures quickly.
  • Ratings to images recorded in the [Jpeg + RAW] mode are applied to both Jpeg and RAW files.
