Material Closed full metal housing, Top cover and bottom cover: brass, black finish
Lens mount Leica M bayonet
Operating conditions 0°C to +40°C

Viewfinder Large, bright-line rangefinder with automatic parallax compensation
Parallax compensation The horizontal and vertical difference between viewfinder and lens is compensated automatically in line with the relevant focus setting. Congruence of viewfinder and actual image.
The size of the bright-line frame matches the distance:
– at 2 m: the exact sensor size of approx. 23.9 x 35.8 mm
– at infinity: (depending on focal length) approx. 7.3% (28 mm) to 18% (135 mm)
– less than 2 m: less than film size
Viewfinder magnification x0.72 (all lenses)
Wide- base rangefinder Split and superimposed image rangefinder shown as a bright field in the center of the viewfinder image.

Focus mode Manual
Exposure  
Exposure metering TTL (exposure metering through the lens), with working aperture
Metering cell Silicon photo diode with convex lens to the top left behind the camera bayonet.
Film speed range Manual setting from ISO 6/9° to ISO 6400/39°.
Metering principle The light reflected by a metering spot in the center of the 1st shutter curtain is metered.
The metering spot has a diameter of 12mm and therefore corresponds to approx. 13% of the full negative format or around 2/3 of the short side of the corresponding
frame in the viewfinder.
Exposure control mode Manual shutter speed and aperture setting, adjustment using LED light balance.
Flash  
Flash unit connection Via accessory shoe
Synchronisation On the 1st shutter curtain
Flash sync speed 1/50s; slower shutter speeds possible.
Flash exposure control Via computer control of flash unit or via guide number calculation and manual setting for the required aperture.
Power Supply 2 Silver oxide button cells (PX76/SR44) or 1 Lithium battery (DL1/3N)
