Leica today announced firmware update 1.196 for the Leica M9 and M9-P cameras. The main improvements are:
Further improvements of SD-Card compatibility.
Implementation of the Lens detection of the new APO-Summicron-M 1:2/50mm ASPH.
Improved power management.
The camera is now measuring battery stability internally. In case of weak battery stability, the camera switches off automatically. The capacity of Li-ion batteries weakens after a certain amount of use. This might lead to improper working of the camera, even loss of images while writing to the SD card. To prevent this, the new firmware will cause the camera to shut off if the camera senses instable battery conditions. Leica recommends replacing older batteries after three years of use. New batteries can be ordered from any Leica dealer (Product Number 14464).
