Fujifilm Announces New X-T1 Firmware Update, Offers Vastly Improved AF

By Anthony Thurston on May 11th 2015

Fujifilm continues to amaze with its steady stream of improvements for currently available products. Today, the company announced a new firmware update for the X-T1, which promises some advanced AF upgrades and key new features.


The new X-T1 Firmware, officially called version 4.0, features some advanced AF system updates that challenge conventional thinking of what can be updated with firmware updates.

Headlining the new AF features is a new ‘Zone’ Mode, which allows users to select a 3×3, 3×5 or 5×5 zone from the normal 77-point AF zone. When combined with the AF-C continuous focusing mode, the camera continues tracking a subject in the selected zone. The 3×3 and 3×5 zones at the center, in particular, offer “extra-fast focusing” with the use of the X-T1‘s built-in phase detection pixels.

In addition to the improved AF tracking and new zone focusing mode, the 4.0 firmware update includes the addition of exposure compensation while in manual mode – something that was previously not an option on the X-T1. The new firmware also makes some changes to the shutter dial operation, making it easier to change speeds without having to move the dial.

Smaller additions include a new Eye-Detection AF mode, Auto Macro Mode, and Improved AF in video, rounding out a pretty substantial update for the X-T1. This new update is pretty impressive, given the rather large firmware update it had at the end of last year.

The new X-T1 version 4.0 firmware was announced today, but will not be available for public consumption until June. I know many of you will be eagerly awaiting it, as I will be very interested to see how much of an improvement to the AF it brings.

    “exposure compensation while in manual mode “….. ???

      Right – what does that do if you’re in manual??

    • Anthony Thurston

      This seems silly to some. But it’s actually quite a popular feature. Sometimes changing the exposure comp is just quicker than messing with other settings, so this gives people who miss this feature the option.

      What settings does exposure comp change while in manual – shutter speed/aperture/ISO? I could see using auto-ISO while being in manual mode and exposure compensation simply changes the ISO setting.

      If you shoot in auto ISO with your shutter and aperture set the dial adjusts the ISO the camera chooses? Meaning the SS and F stop remain the same?

    • J. Dennis Thomas


      Basically, yes. If you manually set the aperture and speed while in Auto-ISO the camera uses the EV comp to adjust the ISO setting to get the necessary under or overexposure. At least that’s how it works with Nikon cameras.

    This could be a game changer if it lives up to the hype. I returned my XT-1 back in the day, but this would be grounds to give it another look.

      I’d wait if I were you. I returned my X-Pro1 and bought another when the “super-fast AF” firmware upgrade was released only to be disappointed yet again.

      Not to knock Fuji users, but many of them really seem to oversell the cameras for whatever reason. I tried every one of the Fuji X’s and I’m still not as impressed as everyone on the internet seems to be.

      So, if I were you I wouldn’t jump into buying another XT-1 right away.

      I second Dennis. I have an X-T1 and AF isn’t nearly as fast as what we read in the reviews and user comments. All those “blazing fast” and “100% success rate” are either lies or over excitement. Truth is, it doesn’t come close to a DSLR.

      And firmware v4 will be better than today but still slower than DSLRs.

      But we all know that don’t we? We all know mirrorless cameras don’t come anywhere close to DLSR AF. At least we should.

      I knew it when I bought the X-T1 and I’m 100% happy with my 50% rate ;)

      I’m also fine with the speed of the AF on the X-T1. It’s AF set up is no where near my 5D3 but it is great for most of what I shoot, as I’m not into shooting tightly framed sports shots. If it can get most of the shots of some kids going mad in a field that’s a good enough test for me.

    I second that. I think sony and the other mirrorless options need to get on board with Fuji.

  5. Derek Schwartz

    I really wish Canon/Nikon did more of this.

  6. Austin Swenson

    I wonder how much better other brand cameras would be if they came out with firmware updates that added more cool stuff like Fuji… Good on them.

    WOOHOO, upgrades!
    You have to love Fuji for continually adding to their features & refining the product.
