Fujifilm · First seen Jul 4, 2026

v1.01 is not the latest firmware for the Fujifilm GFX100S II: the current version is v1.20 (September 2, 2025). Go to v1.20

What's in this update

The firmware update Ver.1.01 from Ver.1.00 incorporates the following issues:

  • When the GF50mm/GF35-70mm lens is attached to the camera body and the lens firmware is updated, in rare cases, “LENS ER​ROR” 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”

  • A firmware bug is fixed that the minor noise sometimes appears on the image depending on the subject when RAW images were processed by image processing software to emphasize image quality-related corrections.
  • A firmware bug is ​fixed that the false coloration on the edges of text in rare cases when shooting the fine text, such as a text chart and enlarging this text for display.
