Fujifilm · First seen Jul 4, 2026

v2.21 is not the latest firmware for the Fujifilm GFX100 II: the current version is v2.50 (March 26, 2026). Go to v2.50

What's in this update

The firmware update Ver.2.21 from Ver.2.20 incorporates the following issues:

  • When the GF50mm/GF35-70mm lens is attached to the camera body and the lens firmware is updat​ed, in rare cases, “LENS ERROR” occurs during the firmware update and the lens stops moving. This revised firmware automatically quits the update to prevent the lens from malfunctioning when detecting the updating error.

Note-1:To enable the above fix, update the camera’s firmware to the latest version before updating the lens firmware.

Note-2:The firmware download for GF50mmF3.5 R LM WR and GF35-70mmF4.5-5.6 WR will be available after this firmware is released.

Note-3:For details, refer to the “FUJINON LENS GF50mmF3.5 R LM WR & GF35-70mmF4.5-5.6 WR firmware download resumption”

  • Wh​en the shutter button is half-pressed at the same time as the “AF ILLUMINATOR” light metering operation, the camera freezes in rare cases.
  • The camera freezes in rare cases while recording movie with an external monitor connected under the following conditions.
