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 and spot metering record predominantly

or exclusively an area in the center of the image are 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.

Notes:

• Exposure lock should not be used in conjunction with multi-ﬁeld

metering, as in such cases selective recording of a single

subject detail is not possible.

• In conjunction with exposure lock (by pressing the shutter

release down to the ﬁrst pressure point), Live View also provides

an exposure simulation feature (see p. 177).

Using the function

1. Aim at the important subject detail (with the metering ﬁeld for

spot metering) or alternatively at another detail with average

brightness.

2. Press the shutter release button (17) to the 1st pressure point

to measure and store the value. 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. A

dot appears between the ISO and exposure compensation

values in the monitor.

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 cancelled when you remove your ﬁnger from the

shutter release pressure point.
