Ricoh GR IV Firmware 1.21

Ricoh GR IV Firmware 1.21 is the software update released by Ricoh Imaging for the GR IV and the GR IV HDF on 10 November 2026. It downloads from Ricoh's official support page and covers both models, which share the same file.

According to Ricoh, version 1.21 improves stability for general performance. The update also carries every change introduced up to 1.20: the AF Point option in Customize Settings Memory, which decides whether the focus point returns to the centre on power-up or keeps the position you chose; restoring User Mode settings when the camera is switched off; and the Connection While Power Off setting in the wireless communication menu.

The process runs from an SD card: copy the file, insert the card in the camera and start the update. Ricoh warns that once version 1.21 is installed you cannot return to an earlier firmware, so it is worth updating with time to spare before an important job and with a charged battery.

In daily use, the Ricoh GR IV Firmware 1.21 offers little spectacle and plenty of peace of mind: fewer unexpected failures in a camera that lives in a pocket and is switched on many times a day. For anyone shooting with the GR IV HDF, the same file covers the special-edition body, with no separate steps or extra downloads.
