The Shutter Release - Leica M Anleitung

Note:
If the camera is out of use for an extended period or is stored in a
case, always turn it off at the main switch. This prevents any power
consumption, including that which continues to occur in standby
mode after the exposure meter is turned off automatically and the
display is extinguished. This also prevents pictures from being taken
accidentally.

ThE ShUTTER RELEASE

The shutter release button (16) has two pressure points:
1. Pressing down to the 1st pressure point
– activates exposure metering and the viewfinder display
– saves the metered exposure value in aperture priority mode,
i.e. the shutter speed determined by the camera (for more
details, refer to the "Metering memory lock" section on p.
183).
– restarts a self-timer delay time that is already in progress (see
p. 198)
If the shutter release button is kept at this pressure point, the displays
remain visible, or if the camera had previously been set to review
mode, it switches back into picture mode. If the camera was
previously in standby mode (see p. 150), it is reactivated and the
display is turned on.
If you let go of the shutter release button, the metering system and
the displays remain activated for around a further 12s (for more
details, refer to the sections under "Exposure metering" on p. 180).
Note:
The shutter release button remains blocked
– if the internal buffer memory is (temporarily) full, e.g. after a series
of ≥8 pictures, or
– if the memory card inserted and the internal buffer memory are
(temporarily) full, or
– if the battery has exceeded its performance limits (capacity,
temperature, age)
2. Pressing the shutter release button all the way down takes the
picture or starts a preselected self-timer delay time. The data is
then transferred to the memory card.
The shutter release button has a standard thread (16) for a cable
release.
