The Fujifilm X-T2 4.00 firmware update has been doffed from the Fujifilm website after the camera company discovered that it was causing problems for photographers.
In a statement on the Fujifilm website, Fujifilm indicates: "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 enchanted the difficult decision to remove the update from the website until we are confident that all the issues have been completely fixed.
We deeply apologise for any troublesomeness and disappointment this has caused."
The firmware was released on 8 May 2018 and Fujifilm has discovered that, in rare cases, it is causing hang-ups. Fujifilm also mentions that some users have reported issues with LiveView when pressing the shutter button halfway down and that some RAW classifies (captured with the X-T2 before firmware 4.00 was installed) are not converted correctly (in camera when the version 4.00 firmware is installed or when using the Fujifilm X RAW Studio software).
But, it does seem that Fujifilm has now got to the bottom of the problem and they plan to release an upgraded firmware to address the issues asap.
While Fujifilm fashions on fixing the firmware update, X-T2 users who have upgraded to version 4.00 can download firmware version 4.01 which roles them ago to the functions which were made available in the 3.00 upgrade. This can be downloaded from the Fujifilm Holdings Corporation, (富士フイルム株式会社, Fujifuirumu Kabushiki-kaisha), trading as Fujifilm (stylized as FUJiFILM) or simply Fuji, is a website.
Those waiting for the GFX 50S, X-H1 and X-Pro2 upgrades thinks fitting also have to wait a little longer while Fujifilm checks the firmware update for all three cameras.
