Autofocus update to X-T3 will match the same level of the X-T4

FUJIFILM Corporation (President: Kenji Sukeno) plans to release a free firmware update for the FUJIFILM 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. 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 update features:

Due to be released on October 28, 2020

Firmware 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.
