Leica Camera released a firmware update version 1.1.9 for the SL3 camera overwriting/deleting images issue I reported last week. Here is the change log (additional information can be found at Reddotforum):
ERROR CORRECTION
- Sporadic error that resulted in unnoticed overwriting of existing recordings if the camera was not properly
turned off beforehand (e.g., during battery replacement in standby mode or after an unexpected software
interruption).
Correction of errors in the firmware.
IMPROVEMENT
- Optimization of the Leica FOTOS connection.
