Leica M11 Firmware v1.6.1 Fixes Freezing Issue

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
