X-T1 FW 4.0 BETA: I have it and share my findings soon ;)

Recommended Posts

A French FujiRumors readers 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 (sometimes even FujiRumors has to sleep). But it's pretty nice to see how well it tracks my dog ;).


I'll share my findings about the FW in the next days in this thread... stay tuned :)


Although the file is circulating on facebook, I decided to remove it, since it's not the final version.

So far so good.  I really do like the new zone AF system. Feels more responsive.  I haven't had any major issues with is. I'm not sure if this is the way it's supposed to works but when face detection and eye detection are turned on, the back button focus does not work... 


I want the back button focus to be the only focus button, but in manual mode you lose zone and wide mode only single point works.

its ridiculous to remove the link.  This firmware will be in XT10 tomorrow.    I bet Fuji themselves release it tomorrow, it does not make sense that lesser camera comes out with Firmware and the owners of a superior camera have to wait for same thing for a week.

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.

Went for a lunch walk, practiced with the 35mm 1.4 and 14mm 2.8


AF-C Wide Tracking is really amazing for tracking trams, cars, horses, etc. Spot on every frame with minimal effort.


The 3x3 zone AF-S focuses very quickly with the 35mm lens. This will probably be my default AF mode from now on.

I liked 5X3 zone AF-S in my short testing here.   Next test which will be the key one -  my 3 year old running!  That wont happen for few days though.....    If that 35 continue its crazy I might seriously consider selling my Sony A7 and 55 1.8 FE lens.

    • I wish I could help. I have read the charts on what these settings save and what it doesn’t....have never been 100% comfortable using.  But never had that particular issue.
    • I setup my C1 for bird and action settings. ISO3 (shutter 2000, 125-6400ISO, AF zone, bird). If I'm on a single ISO setting and select C1 it will not go to the AUTO3 setting. If I'm currently on auto iso1 or iso2 it will go to iso3 but the top iso value displays as 1600 even though I set it to 6400 max)? I basically still need to go in and manually change to auto3 to get it to work. Any thoughts would be appreciated.
    • LCD Problem on my X-H2. Camera is 3 months old.  Just this week, LCD was not going on, or it was on then went off, while opening it and turning it outward. Eventually it would come back on after a minute or two. Doesn't happen all the time, but did happen a few times while hiking in cool weather. Has anyone else experienced this yet? I have the settings so that the LCD goes off when I'm using the EVF and I know where that sensor is, so its not user error. I know there have been issues with Fujifilm LCDs in the past, so I'm concerned that this will get worse and I'll have to give it up for a month while its repaired. I'm still within the Amazon return window so considering sending it back for a replacement. All comments and suggestions are welcome and thanks!

    • There are several ways to fix that. Try this, go to System Preferences, click Security & Privacy, then select the Privacy tab. Scroll down and click Full Disk Access. There should be a little + symbol somewhere, click on it and you should be given a dialog box to find the app you want to add. Select it. Now, along the way you will have to enter your password (assuming you have permission to add / delete applications, etc.) to give permission for these thing to happen. An easier way is to delete the app, empty the trash, restart the machine, and reinstall the application, only this time give it the needed permissions as you are going. As far as the tiff files go, it depends on the converter you are using. If they export in 16 bit tiff format, (do not use eight bit) you should have the data but when you open it in your editor, it will have the selected profiles applied as a starting point. ie your white balance, film simulation, etc. etc. because that information is embedded in the tiff from the raf, and used by the editor as a starting point to display the image. Some manufacturers' raw files are actually tiff files with a little proprietary info added in, I have read that Adobe's DNG format is just that as well, a tiff file with a few other things tossed in for good measure. Fujjifilm is now using tiff as a storage option along with .jpg and .raf in their latest camera releases. It is a good format.
