Today, Leica has released a new firmware update for the M11 digital rangefinder. Where the last firmware introduced new features, version 1.6.1 focuses solely on a few bug fixes. Notably, this firmware is designed to address the intermittent camera freezing issue that some M11 users have been experiencing recently. And while this issue only impacts a small percentage of users, we do recommend the installing update for all M11 owners as it will only increase the stability of the camera. Along with the camera freezing issue, an even more rare exposure error has been fixed, along with minor bug fixes and general performance enhancements.

Improvements and Fixes

  • An error that caused the device to freeze has been fixed
  • A cause for the sporadic occurrence of overexposure has been fixed 
  • Additional bug fixes and performance improvements

Download M11 Firmware v1.6.1

To download the firmware file, simply click the button below. You'll need to drag and drop the downloaded firmware file onto an SD card which was freshly formatted in the M11, then insert the card into your Leica M11 with a fully charged battery. Navigate to the Camera Information menu to access the firmware update option. Don't try to open the firmware file on your computer – just copy it onto the SD card into the root directory.

    Hi, I have faced freezing issues since December, I recently replaced the SD card. I am looking forward to installing this update however the firmware upgrade is not enabled / cannot install 1.6.1 (LEICA_M11_V1.6.1.FW).

    Not sure what exactly is going on but I am skeptical.

    I downloaded the update file from the link in the email I received from Leica. Drug the file onto a freshly formatted SD card, inserted the card in the camera and performed the update. The update took about 3-4 minutes. Side note: before the update started it asked if I wanted to save my profiles to the card. I selected YES. After the update the profiles were restored.

    I have just upgraded from my M (Typ 240) to a brand new M11 and immediately installed the latest firmware 1.6.1
    Sadly, I still had two occasions today, where the M11 froze. I have not yet been able to make out any particular camera settings that might lead to the bug. I suspect it is to do with the live view.

    I have installed the latest firmware but my camera still has an issue freezing up and had to send to Leica for repair it is so frustrating and disappointing spending 8000 on a camera and then need to be sent over to Germany to get it fixed and who knows for how long

    I went through the procedure as outlined in your website, but when I got to Select Camera Firmware Version I could not progress further. I tried it again 3 times but nothing progressed me

    Yes, same here, new firmware but still on average one freeze a week.

    Doesn’t fix the issue. Bought a brand new M11 16th June, and it’s freezing. Dealer said I’m the 3rd customer to report it in their latest batch

    The camera still freezes sometimes. Almost once every shoot. Definitely missed shots due to this. Not the best experience tbh.
