M8 FAQ

1. The sensor is a 1.3 crop, the recorded field of view of lenses designed for FF (35mm) changes accordingly.

M8 Firmware History

  • 1.06
  • 1.09 (Dec 2006)
  • 1.091 (28 Feb 2007)
  • 1.092 (05 Mar 2007)
Version 1.092 Includes: In Review mode the bar above the image is black and now includes displays for the shutter and ISO speeds
as well as the image number. The clipping function is now accessible directly in Auto Review mode,
i.e. without having to press the INFO button first. The color rendition with Adobe Camera Raw was improved. If Auto Review 
and Histogram are both selected in the menu, this is now indicated as „Hold/Histogr.”  The word „disabled” has been replaced by „off”. 
Numerous internal procedures were improved and so-called bug-fixes implemented. 


  • 1.102 (14 Mar 2007)
Version 1.102 Addresses: Image quality problems resulting from the M8 sensor sensitivity for infrared light.
Depending on the angle of the light it can lead to color offsets near the image edges with focal lengths from
16 to 35mm and will give an undesirable magenta-colored offset effect. Leica has therefore recommended the use of special Leica UV/IR filters.
Together with coded lenses, this new firmware version corrects these color offsets. 
  • 1.107 (27 Jul 2007)
Version 1.107 Includes: Changes within the firmware allowing Leica Camera an even saver and more efficient production process.
Modification of internal procedures, optimisation of the general image reproduction and the functional features of the
LEICA M8 has been accomplished.
  • 1.110 (05 Nov 2007)
Version 1.110 Includes: 6 Bit lens codes for Summarit-M lenses 35, 50, 75 and 90 mm; Time shortened between pre-flash
and main flash in M-TTL mode with flashes LEICA SF24 D and SCA compatible flashguns function of the central setting 
wheel on the camera back improved (unintentional scrolling of the menu now prevented) battery capacity display improved 
Change in the French menu: «Marche +UV/IR» instead «Marche avec» 
  • 1.201 (02 Feb 2008)
Version 1.201 Includes: New and considerably improved algorithms for the automatic white balance (AWB), 
Bug fixes: The following effects have been   remedied: With certain SD card types, images were bouncing while being reviewed.
In few cases, wrong exposures were reported when the camera was released from stand-by mode.
In the Exif data, the Max-Aperture-Value of the TRI-ELMAR-M 16-18-21mm/f4 ASPH was incorrect.
