Last week, Fujifilm released firmware version 4.0 for the Fuji X-T2, which brought the two-year-old camera almost on par with the newly-released Fuji X-H1. The update was hailed as yet another phenomenal example of Fuji's 'Kaizen' policy, but we may have all jumped the gun. Today, Fuji rolled back the update after users who had updated discovered some major issues with v4.0.

The roll back was announced in a note on Fuji's website, where General Manager Toshi Iida writes:

It has been brought to our attention that there are a few issues with the recently released X-T2 ver 4.00 firmware update. We have therefore taken the difficult decision to remove the update from the website until we are confident that all the issues have been completely fixed.

We deeply apologize for any inconvenience and disappointment this has caused.

The malfunctions listed include issues converting RAW files captured by the X-T2 before firmware 4.0 was released, live view flickering under certain conditions, and the rare chance of a "hang-up" while shooting.

The good news is that Fuji has "identified the problem" and are planning to re-release the much-anticipated update "as soon as we can." The bad news: for now, it's highly recommended you "update" to version 4.01, which is actually a roll back to the stable version 3.0.

Finally, due to this hiccup, Fujifilm has also announced that planned firmware updates for the GFX 50s, X-H1, and X-Pro2 that were due out later this month have been delayed so Fuji can more thoroughly test them.

Release Notes

To all loyal Fujifilm X Series customers and photographers,

It has been brought to our attention that there are a few issues with the recently released X-T2 ver 4.00 firmware update. We have therefore taken the difficult decision to remove the update from the website until we are confident that all the issues have been completely fixed.

We deeply apologize for any inconvenience and disappointment this has caused.

Toshi Iida

Details of the Problem

We have discovered malfunctions in the firmware ver.4.00 released on May 8 2018. They are as follows:

  1. When RAW files, which were taken by X-T2 (before firmware ver.4.00), are converted in camera (ver.4.00) or by “FUJIFILM X RAW STUDIO”, they are not converted properly.
  2. When pressing the shutter button halfway under certain conditions, the live view can flicker.
  3. In rare cases, a hang-up can occur.

We have identified the cause and plan to release the upgraded firmware to address the malfunctions as soon as we can.

In the meantime, for customers who have upgraded the firmware to ver.4.00, the firmware ver.4.01*, whose functions are same as ver.3.00, have been posted on our website. Please download it and update your camera.

  • *Ver.4.01 doesn’t include the additional functions of ver.4.00.

Again, we sincerely apologize for the inconvenience caused.

Note

We announced the firmware update for GFX 50S, X-H1 and X-Pro2, which was planned in May 2018, on the Global website on 12 Apr 2018. However, it will be postponed because we need more time to check the firmware for the three models. For detail, we will inform you later.
