Fujifilm Manager: “We Are Committed to Bring X-H2S Autofocus Features as much as Possible to Older Models (X-T3/X-T4)”


  • A limited number of Fujinon XF150-600mm f/5.6-8 lenses is now in stock at Amazon US here (at the moment also shipped and sold by Amazon).

When asked if the X-T4 and X-T3 will profit from the new autofocus algorithm of the Fujifilm X-H2, the service manager for Fujifilm Germany says:

First off we have to say clearly that the Fujifilm X-H2S uses a new stacked sensor and a new processor, who are largely responsible for the fast readout and autofocus speed and at the end allow the new algorithm to realize such an autofocus performance.

This means you can’t bring that kind of performance 1 to 1 to other models like the X-T3 and X-T4, who use an older sensor and processor.

But we are committed to bring new features as much as possible to older models via firmware update

This is not Google translated from German, but translated by myself for you in the most accurate way possible, in order to avoid misunderstandings.

Look, when my Fujifilm X-T4 sees faces in trees and branches, I am sure that this is not a limitation of the sensor and processor, but of the algorithm itself. And that’s true also for the real-time Sony alike autofocus tracking, which disappointed me a bit during the wedding I photographed and that could be significantly improved via firmware update also on older cameras.

That’s why I believe that the new algorithm alone would already give us a huge improvement on older cameras, at least for face and eye detection.

And if there would be also an improvement in zone/area tracking, I could also live without subject/animal tracking on my Fujifilm X-T4, which probably are more complex to implement and really require all the latest and greatest 5th gen stuff.
