ATTACHING THE FLASH UNIT

When attaching a flash unit, you should ensure that the

foot is securely fitted in the flash shoe (1.20) on the

Leica M Monochrom and the clamping nut (if fitted)

is tightened to prevent it accidentally falling out. This

is particularly important for flash units with additional

control and signal contacts, because if the flash moves

from its position in the flash shoe the required contacts

can be broken, leading to malfunctions.

Note:

Before attaching the flash, the camera and the flash

unit must be turned off.

FLASH MODE

Fully automatic camera-controlled flash operation

is available on the Leica M Monochrom when using

system-compatible flash units as described in the

previous section, in both exposure modes – aperture

priority mode

and manual setting.

In addition, automatic illumination control is operational

in all three exposure modes. This means that in order

to ensure a balanced relationship between flash and

available light at all times, the flash power is reduced

by up to 1

EV as ambient brightness increases.

However, if the ambient brightness plus even the

shortest possible flash sync time of

180

s would cause

overexposure, the flash will not be fired in aperture

priority mode. In such cases the shutter speed is

governed by the ambient brightness and is shown in the

viewfinder.

In aperture priority mode

and with manual setting,

the Leica M Monochrom also allows the use of creative

flash techniques such as synchronization of flash firing

with the 2nd shutter curtain rather than the 1st, as is

usual, and flash with slower shutter speeds than the

sync speed of

180

s. These functions are set on the

camera using the menu (for more details, refer to the

relevant sections below).

In addition the Leica M Monochrom transfers the

set sensitivity to the flash unit. Provided it has these

displays and the aperture manually set on the lens

is also entered on the flash unit, this enables the

flash unit to automatically adjust its range values

accordingly. The sensitivity setting cannot be changed

from the flash unit.
