I (experienced photographer, 64) own a Ricoh GRIIIx for about two months now. Shoot raw + jpg. Every now and then the camera will show an error message: “unable to store image.” It will then shut down (screen goes black, lens retracts). In this case only jpgs will show when transfing files to my PC. I’ve reformatted the memory cards (SanDisc) in camera, used another memory card (also reformatted in camera), the issues persists even after correct firmware update 1.20. The problem seems to be experienced by several others owners of GRIIIx and GRIII. Do you have any idea what to do? Your help is much appreciated.
