Exposure Lock - Leica M Operating Instructions Manual

EXPOSURE LOCK

For compositional reasons, the most important part of the subject
is often not in the center of the picture, and as a result such
important parts of the subject may be excessively light or dark.
Center-weighted metering, however, records predominantly or
exclusively an area in the center of the image and is calibrated to
an average gray scale value.
Subjects and situations of this type can be overcome very easily
even in aperture priority mode, using exposure lock.
Using the function
1. Aim at the important subject detail or alternatively at another
detail with average brightness.
2. Pressing the shutter release button
pressure point activates metering and storage.
• As long as the pressure point is held, a small red dot
appears in the viewfinder at the top in the digits line for
confirmation, and the exposure time no longer changes even
if the lighting conditions are different.
3. Keeping the shutter release pressed, move the camera to
capture the final trimming,
4. The shutter can then be released using the exposure originally
determined.
Changing the aperture setting after using exposure lock has no
effect on the shutter speed, and will lead to an incorrect exposure.
Exposure lock is canceled when you remove your finger from the
shutter release pressure point.
