A French FujiRumors reader spotted the Firmware 4.0 file on Facebook… and for the sake of science, I decided to update My Own X-T1 with Firmware 4.0 and test if it works 🙂
It’s really late at night here, and I will do proper testings tomorrow. But it’s pretty nice to see how well it tracks my dog ;).
IMPORTANT NOTE: Although the file is circulating on facebook, I decided to remove it.

…voluntary please 😉
let me do some proper testing tomorrow… but so far, everything is fine on my X-T1 😉
So is the official release same as the leaked beta?
I volunteer too 🙂
Well, considering the official release is less than a week away, Fuji should be in their final regression/stabilization period of code testing, so hopefully no major bugs will still be present…but you never know.
Just updated my X-T1 Its amazing truly a new camera
Any issues so far?
when face detection and eye detection are turned on, the back button focus does not work… still playing with it.
Did the update wipe your customizations?
Nope, my Q menu, short cuts and auto iso settings are all intact.
Jon, please email me the link or file at keoni@ahlo.com. Thanks!

You are the devil. 🙂
it’s better to wait… it’s just a few more days
Now there is one of you on each shoulder… 🙂
i’d say somebody in fujiland is gonna be looking for a new job tomorrow
Or it could be on purpose – free testing and feedback from real customers, with a week to spare and react to any issues 😉
Cool. I’ll wait for the official release. Won’t be long now.
Same here. My lens is sent back for an exchange. I don’t need it very soon.
Guys, beware of this… If you install this version, your camera will see it as version 4.0 and when the new version will be released officially, it won’t allow you to upgrade because the camera won’t see a difference in version number.
Then how do testers update their cameras?
With Nikon (i used to test for them) versions were like this: 4.0.0a or any letter identifying pre-release version. Also we had a tool to roll-back the camera to a previous version. I don’t think Fuji allows you to roll-back to previous firmware version… At least i’ve never tried it.
It is likely that the beta version has a beta flag that’s not displayed by the camera but visible to FW updater, so it will update just fine. Another possibility is that it’s a final version leaked ahead of a scheduled release date.
I’ve downloaded it, but still contemplating.
My bad. I glanced at it and apparently I was wrong
Pretty sure a 4.1 version will be released soon. Not a big deal.
You could obviously change the version number to 3.9 before installing it and you shouldn’t run into any issues. Still a small risk obviously.
Nope, my fault.
link please???? I want to update now

I will wait until it gets official.
Give it to me.
Where is the link?
I don’t want to wait. 😀
release the link.
I downloaded the version yesterday as well and all seems to work very well.
If someone could send me the link that would be awesome. I have two X-T1s and I’d love to test it on one of them ( got a wedding this weekend so could be super useful ).
Tonight i can send you the Link …
see my other comments made for David B
Got it thanks:)
Amazing improvement visible using the 35mm. Very happy. Would love some feedback on the 14mm f2.8 also, any difference?
if this fw is already good, I hope to see before 25th June.
Can I please get a link to the 4.0 update. It’d be a happy day if I can get my XT1 updated
