M9 Firmware Version 1.196
- Further improvements to SD-Card compatibility.
- Implementation of Lens detection for the new APO-Summicron-M 1:2/50mm ASPH.
- Improved power management – The camera is now measuring battery stability internally. In the case of a weak battery, the camera switches off automatically.
- Before this update, using older batteries could have lead to camera crashes and banding stripes (under certain conditions).
Leica is recommending that batteries be replaced for the M8 and the M9 after 3 years.
Here’s the full list of improvements in this update.
