For some reason, yesterday a photographer decided to share the X-T1 Firmware 4.0 file with the whole world on Facebook. People began to install it, and a kind French FR-reader, shared the link also with FujiRumors.

Of course, for the sake of science, I had to install it on my own X-T1. But I’ve decided to take off from FujiRumors and the Fuji X Forum, since this is a BETA version of the firmware. The final version will be available on the 25th. Other sites are still offering it, like the Spanish Forum Fujistas. But I do not recommend to update, since it could have bugs, that Fuji still has to sort out. It could damage your camera, and no warranty will cover it. Just wait a few more days.

I hope to find some time later today, to test it by myself. What I can say so far, is that in AF-S the 35F1.4 for sure feels more responsive. Still have to do proper AF-Tracking tests.

Anyway, I’m not the only one with FW 4.0, and more feedback can be read in the comments of this FXF thread. I’ll share a few here… to read all the comments click here.

“The 35mm does not pulse back and force anymore it just locks on!! amazing!! :).”

“Here are my results so far.  I only have 3 Fuji X lenses currently.

35/1.4  the most dramatic change.  Lens just gets to focus without rocking back and forth. Amazing for this lens. All of the sudden it is like a different lens!!!
18-135.  I tried to lower the light in my bedroom and focus at tele end.  It is usually a slow lens to focus in low light.  Result – much quicker acquisition.
56/1.2    seems to be no changes whatsoever with how that lens focused with previous firmware.”
