Technical data

Camera type Compact 35mm range- and viewfinder system

camera with mechanically controlled shutter.

Lens connection Leica M bayonet.

Lens system Leica M lenses from 21-135mm

Exposure metering Exposure metering through the lens

(TTL), selectively with working aperture.

Metering principle The light reflected by a metering spot in

the center of the 1

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

of the

short side of the corresponding frame in the viewfinder.

Metering range (at ISO 100/21°) From 0.03cd/m

125000cd/m

at room temperature, normal humidity and

aperture 1.0. At ISO 100/21° this corresponds to EV-2 to 20

or f/1 and 4s (B-setting) to f/32 and 1/1000 s. Flashing of the

left triangular LED in the viewfinder indicates values below the

metering range.

Metering cell for available light (continuous light measure-

ments) Silicon photo diode with convex lens to the top left be-

hind the camera bayonet.

Film speed range Manual setting from ISO 6/9° to ISO

6400/39°.

Exposure mode Manual shutter speed and aperture setting,

adjustment via LED light balance.

Flash exposure control

Flash unit connection Via accessory shoe with central

contact and/or standard flash connection socket.

Synchronisation On the 1

shutter curtain.

Flash synchronising 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.

Viewfinder

Viewfinder principle Large, light bright-line range- and view-

finder with automatic parallax compensation.

Eyepiece Adjusted to –0.5 dpt.. Corrective lenses from –3 to

+3 dpt. available.

Image field limitation By projection of pairs of bright-line

frames: For 28 and 90mm (90mm only on LEICA MP 0.85) or

for 35 and 135mm (35mm only on LEICA MP 0.58), or for 50

and 75mm. Automatic projection when lens is attached. The

desired frame can be projected using the frame selector.

Parallax compensation The horizontal and vertical differ-

ence between the viewfinder and the lens is automatically

compensated according to the relevant distance setting, i.e.

the bright-line frame automatically aligns with the subject

detail recorded by the lens.

Matching of viewfinder and film image The size of the

bright-line frame corresponds to an image size of 23 x 35mm

at the shortest setting distance for each focal length. With the

infinity setting, depending on the focal length, approx. 9 %

(28mm) to 23% (135mm) more of the image is recorded than

the corresponding bright-line frame shows.
