Today, Leica Camera has announced a major new firmware update for the Leica M (Typ 240), firmware version This update includes a large number of new features, some quite significant, and incorporates many of the changes that customers have requested and dealers have requested. The official release from Leica:

Leica Camera is pleased to inform you that a new firmware, version is available for the Leica M (Typ 240) effective immediately. The new firmware includes many improvements which enhances the functionality of the camera. The installation instructions and the firmware file are available at:

All newly produced Leica M (Typ 240) cameras will have the latest version of the firmware, as a factory setting.

The new firmware offers the following improvements:

  • Improves description of the lens type in EXIF-DATA.
  • Live view is now possible with every lens (including older screw lenses via 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 virtual horizon (level) is now visible in Live View, overlaying the live image. This additional info-screen is enabled using the menu item “Horizon”.
  • New menu item “Exposure Simulation”:
  • Exposure simulation – Permanent: Live View accurately shows images 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, 2x 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 3:4/6:7/1:1/16:9 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 – 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 is 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” – offers improved visibility and the color of focus peaking can be set to red, green or blue.
  • Better display of GPS location data:

Position is now shown for JPEG files in Adobe Lightroom and where the signal is weak; the last position is now deleted after 5 minutes instead of 24 hours as in previous firmware.

  • The new firmware provides bug fixes for the following:
  • Live View at high temperatures
  • Light metering (Live View)
  • Sensor cleaning function

    I found that after installing the new version of the firmware for my M240 that the exposure metering was erratic and all over the place – but everything returned to normal once I had performed a camera “reset” using the Menu “Reset” Item. This saved my camera from the garbage can.
