I bought the excellent OM System’s OM-1 camera in may 2022. Since then there have been two firmware updates for the camera. There have been a few reports of people failing to update the firmware, resulting in a camera that won’t even start, and which needs to be fixed by OM System’s support. So I was a bit apprehensive of doing it, but it went fine for me. This blog article describes how I did my firmware update, and should also be of interest to those OM-1 owners who only use Linux.
