Today, Leica released a new firmware version 2.0 for the M8 digital body. This new firmware release provides support for larger size SDHC cards, up to 32Gb. Leica still recommends Extreme III and Professional versions made by Lexar and SanDisk as being the most compatible. Whichever cards you use, it is nice to break the 2mb barrier!
Leica also says that an addition is made for an AUTO-ISO setting allowing for options with maximum ISO values and minimum shutter speeds.
Finally, Leica makes it clear that after updating to firmware version 2.0, you CANNOT go backwards to a previous version!
I have downloaded the firmware and I will test it over the next few days to let you know if I find anything of concern. You can get the firmware from the Leica web site or Visit the Download Center for the M8 here.
EDITED: changed 32mb to 32Gb.
