Leica has released a firmware update for its M Typ 240 camera with a huge list of improvements and bug fixes. Firmware is available at Leica's website, and the full list of updates and improvements can be found below. 

Among the new features are: 

  • Live view photography with every lens - even those attached with an adapter. 
  • Expanded Auto ISO ranges and Auto ISO in manual mode. 
  • Direct EV correction via the thumb wheel without trips to the menus. 
  • Video recording at 1/25th of a second instead of 1/24th of a second to reduce flicker. 
  • Better GPS location display, compatible with Lightroom. 

Additionally, several bugs in live view and metering were fixed with this update. 

Improvements – Leica M (Typ 240) Firmware Version

  • Improved description of the lens type in Exif-Data
  • Live view is now possible with every lens (including older screw lenses via an adapter) using "manual lens detection"
  • A "Video off" option is now available in the Set menu (see submenu item "Video recording")
    The M-Button on the Top-cover is deactivated when this option is chosen.
  • The Horizon (level) is now visible in Live View, overlaying the live image. This additional infoscreen is enabled using the menu item "Horizon"
  • New menu item "Exposure Simulation"
    - Exposure simulation -> Permanent: Live View accurately shows image brightness according to the shutter speed and aperture set in manual exposure (as long as the chosen exposure time is shorter than 1/30s)
    - Exposure simulation -> Release button half-pressed: Image brightness in live view is adjusted for best visibility, regardless of the actual exposure. Half pressing the shutter button shows the actual exposure.
  • Extended Auto ISO options
    - All Auto ISO options are now visible using the ISO button
    - Extra options for "Maximum Exposure Time" - 1x, 2 x, or 4x focal length - can be selected to help avoid camera shake when using auto ISO and long lenses. 
    - "Auto ISO in M mode" is now offered as an option. This varies ISO sensitivity for correct exposure when shutter speed and aperture are set manually.
    - Alternatively the camera chooses the previous manually chosen ISO speed
  • Crop marks
    - In Live View, new crop marks for 3:4 / 6:7 / 1:1 / and 16:9 aspect ratios can be displayed. By pressing the up/down keys, the crop marks are superimposed on the live view screen (without additional information)
  • Korean language
    - Korean is now available as a menu language
  • During video recording, 1/25s is now used instead of 1/24s. This reduces flicker effects with 50Hz mains voltage
  • Exposure bracketing settings are now saved when the camera is switched off
  • Direct exposure correction
    - An "EV correction" option in the menu enables direct adjustment.
    - So EV compensation can be altered by turning the thumb wheel, without having to press additional buttons.
  • New Light Metering Mode "Classic / LV disabled"
    - In this mode, only Classic light-metering is possible; the LV button is disabled to avoid the activation of live view by accident.
  • New menu item "Focus Peaking"
    - For improved visibility, the color of focus peaking can now be set to red, green or blue.
  • Better display of GPS location data
    - Position is now shown for JPG files in Adobe Lightroom®
    - Where the GPS signal is weak, the last position is now deleted after 5min instead of 24h as in previous firmware versions.
  • Bugfix in Live View at high temperatures
    - Occasional malfunction of Live View at high temperatures has been fixed
  • Bugfix in light metering (Live view)
  • Bugfix regarding sensor cleaning function
