Viewfinder: Viewfinder principle Large bright line frame viewfinder/rangefinder with automatic parallax compensation. Viewfinder lens optimal visibility of all
bright line frames whatever the lighting situation. Image field limiter By activating two bright lines each : for 24 and 35mm / 28 and 90mm /
50 and 75 mm. Magnification 0.68x (with all lenses). Large basis range finder Combination of split and superimposed image range finder shown
as a bright field in the center of the viewfinder image.
Lenses: Lens connection Leica M bayonet with additional optical scanning device for the identification of all 6 bit-coded lenses.
Lens system Current 6 bit-coded Leica M lenses with a focal length of 16-90mm. Almost all Leica M lenses with a focal length of 21-90 mm manufactured
from 1954 can also be used without 6 bit-coding. 6 bit-retrofitting possible for virtually all lenses.6 bit-functions Lens-dependent reduction
of system-specific vignetting. Identification of picture file with lens information to simplify digital archiving. Coordination of flash reflector with motor
zoom flash units. Auto slow sync function with automatic mode.
Exposure control: Automatic mode (Auto) Automatic determination of correct shutter speed with manual aperture preselection with relevant viewfinder display.
Manual exposure Independent selection of shutter speed and aperture - camera exposure check visible via LED light balance shown in the
viewfinder.
Picture-taking modes: S Single frame picture-taking, for one shutter release whenever shutter is pressed. C Continuous shooting with 2 pictures per second and 10 picture
in series. Automatic release mode Selectable with either 2 s and 12 s visualization of delay time via one of the LEDs visible from front of camera in
viewfinder window.
Controls/display elements: display elements
Front of housing Lens release; image field selector Top of housing Main switch and shutter release; shutter speed setting dial, status LCD display :
indication of number of frames remaining and residual battery capacity. Rear of housing 2.5" color monitor, setting ring for navigation in menu
and magnifier function in 4 levels ; 4x direction buttons for navigation in menu and in image details, Menu button, Play button, Delete button, Protect

quality evaluation of photographs, exposure control via RGB tone value histogram with identification of light image details without detailing
(can also be used with zoom-in), control of sharpness of focus, display of quality parameters selected and display of lens focal length used (with
current 6 bit-coded lenses) Image view sizes 9 thumbnails, 4 thumbnails, single frame display as well as magnification in four levels up to 100%.
Picture parameters menu - Main menu: Pressing the Set button allows the following parameters relevant to the picture to be changed and selected : User profile, Sensor sensitivity, Manual exposure compensation, White balance, data format, picture resolution. Main menu Pressing the menu button allows settings such as color monitor contrast or selection of color space to be made in the Main menu. Menu languages German, English, French, Spanish, Italian, Japanese, Chinese.
Picture resolution: DNG 3916 x 2634 pixel (10.31 MP); JPG 3936 x 2630 pixel (10.35 MP), 2952 x 1972 pixel (5.8 MP), 1968 x 1315 Pixel (2.6 MP),
1312 x 876 Pixel (1.15 MP).
Data formats: DNG (Digital Negative Format not specific to any camera manufacturer), 2 different highly compressed JPEG levels.
DNG file information 16 bit-color resolution, 10.2 Mbyte file size per picture.
Storage medium: SD cards up to 4GB.
White balance: Automatic, 6 presettings, manual white balance, color temperature input from 2,000 K to 13,100 K.
Color spaces: Adobe RGB, sRGB, ECI RGB.
Viewfinder display: LED symbol for flash status, four-digit seven-segment LED display with dots above and below (display brightness always adjusted to ambient brightness)
for : display of automatically determined exposure time with automatic mode, indication of use of metered value storage, warning of exposure
compensation, warning that metering range is overshot or undershot. LED light balance with two triangular LEDs and one center circular LED as an
aid when setting exposure manually.
Metering: TTL metering heavily center-weighted with preset working aperture. Measurement principle Measured by light reflected by a white blade in the
middle of the metal-blade slotted shutter. Metering range EV 0 to EV 20 at room temperature 20° C, aperture 1.0 and ISO 160/23°.
Measurement cell Silicon photo diode with collection lens, positioned at center lower edge, on bottom of camera.
Flash metering / control: Principle of M-TTL flash technology: An extremely short metering preflash activated immediately before the picture is taken is used to measure the output light required for the exposure. Connection: M-TTL Guide Number Control with metering preflash via accessory shoe SCA 3502 (from version M4) or with Leica flash SF24D.
Flash sync time: Fast 1/250 s provides for creative open aperture photography even with bright ambient light. Manual flash sync times from B (bulb) to 1/250 s.
Automatic mode Auto slow sync : automated extension of longest flash exposure time to rule of thumb 1/focal length in seconds.
(only with 6 bit-coded lenses). Selection of long flash sync times e.g. up to 1/8 s for balanced flash with available light shots with automatic mode.
Shutter and shutter release: Shutter: Micro-processor controlled metal-blade slotted shutter with vertical movement. Shutter speeds: In automatic mode (A) steplessly from 32 s to 1/8000 s. Using manual setting 4 s to 1/8000 s in half steps. B for long exposures of any duration.
Activation of shutter: Three-stage activation depending on pressure level : 1. Switch-on of camera electronics and activation of metering
2. Metered value storage (with automatic mode) 3. Shutter release (standard thread for cable release included).
Power supply: Lithium-ion rechargeable battery with 3.7 V and 1900 mAh.
Computer interface: 5-pin standardized mini USB port for fast USB 2.0 data transfer to computer.
Camera housing: Material Closed solid metal housing made of a highly stable magnesium alloy for long-lasting professional usage. Black synthetic leather covering.
