Fujifilm GFX 50S firmware `v4.51`

Fujifilm · First seen Jul 4, 2026

v4.51 is not the latest firmware for the Fujifilm GFX 50S: the current version is v4.52 (November 28, 2024). Go to v4.52

What's in this update

The firmware update Ver.4.51 from Ver.4.50 incorporates the following issue:

When the GF50mm/GF35-70mm lens is attached to the camera body and the lens firmware is updated, 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”
