Leica are advising owners of the Leica M9 to avoid certain Sandisk Extreme memory cards, until they are able to provide an updated firmware to provide support for the UHS-1 cards.
From Leica: Status 08.11.2011
(Update to status report of 11.10.2011)
A new firmware version that includes an update of the SD card driver has now been tested. A broad-based field test has been carried out in association with a large number of beta testers. We would like to thank all customers who expressed a willingness to help with this.
As a result, considerably more stable general performance has been identified with all SD card types. In order to make this improvement available to all customers immediately, the firmware version 1.174 is now available for download on the Leica homepage.
Even so, we still have to recommend not to use the following two types of cards, since we have experienced sphoradic difficulties with them during the test phase.
- San Disk Extreme Pro SDHC I UHS-1 (all card sizes)
- San Disk Extreme HD Video SDHC I (all card sizes)
We would like to specifically point out that this is not implying a general fault on the side of these cards. It is only that at the moment, a 100% compatibility of the M9 with these cards cannot be warranted.
Support for these memory cards is still in development and we will provide a further firmware update for download after successfully testing compatibility.
Thank you for your valued understanding.
