Leica M11 Firmware Update 2.6.0 has been announced to coincide with the arrival of the new M EV1 camera last week. It offers new white-balance adjustment options and enhanced lens detection when using Leica M lenses with six-bit coding. It covers all M11 variants, including the M11-D and the M EV1.
White balance
The new function “White Balance Adjustment” allows the user to make custom changes to the sensor white point calibrated ex-works. This adjustment will affect the automatic white balance as well as the fixed presets (Film Style).
Lens detection
Lens detection now offers additional flexibility when using Leica M lenses with six-bit coding. Even if the lens type is detected automatically, the user can now additionally select another lens type from the list of M lenses. The list is available for all profiles and will be included when profiles are exported to an SD card.
Dust protection
In a third improvement to the firmware, the Dust Protection function can now also be controlled via Leica FOTOS (Version 5.5.1 and higher).
Error correction
The updated firmware repairs several known bugs:
- In rare cases, the connection between the camera and smartphone was severed by the operating system during image downloads and could not be restored afterwards. This issue was resolved.
- A bug was fixed where, in exposure bracketing with Auto ISO, the second and third shots were at times taken with unnecessarily high ISO values.
- The issue where images were sometimes misaligned after being transferred to the computer if the camera was quickly rotated from horizontal to vertical during shooting was fixed.
