One thing that makes the Ricoh GR Series cameras so special is the continued updating of firmware. Whether it's the Ricoh GR II, III, or IIIx, Ricoh Imaging continues to offer new features, keeping the cameras up to date and on pace with competitors. The latest version as of October 2021 is 1.5, but this process will work with future updates as well.
In this video, I give a simple, yet brief description on how to download, install and update the latest firmware from Ricoh for the Ricoh GR III. The same description applies for the new Ricoh GR IIIx updates as well. Along with some interesting JPEG/RAW editing updates, as well as a 4:3 and 16:9 in-camera crop feature, the 1.5 firmware allows for Eye-detection (an upgrade from the previous Face-detection only feature). While the previous version usually nailed focus on most portraits I've shot with the GR III, the eye-detection is even better. I will have future videos featuring these new upgrades soon.
