Fujifilm X-T4 FW 1.02

A few weeks ago, Fujifilm released firmware 1.02 for Fujifilm X-T4 cameras (I did update mine via Fujifilm Smartphone App, and you?).

Officially, it improves IBIS (with great results) and fixes some bugs.

There was not mention of anything autofocus related, but as FujiRumors reported here, one of the hidden improvements should be better video autofocus with DC motor driven lenses (such as the Fujinon XF56mm f/1.2, which until firmware 1.01 was a horrible lens for video AF).

Now the French channel Les Guides Fujifilm & Sony tested Fujifilm X-T4 firmware 1.02 using the XF56mmF1.2 and also compared it to firmware 1.01.

What he notices:

• Firmware 1.01
  – many hesitations and pumping
  – not acceptable
• Firmware 1.02
  – walking faster: wow, it reacts pretty well
  – when his subject walked slowly, it did not hesitate at all
  – pumping movements he had with firmware 1.01 are mostly gone, almost perfect
  – when his subject moves out of frame and then back in frame, the camera detects his face and does not hesitate when locking on his face
  – the focus moves more gracefully

He rightfully wonders why Fujifilm didn’t mention this big improvement on his official firmware 1.02 page, but luckily there is FujiRumors for that ;).
