Stop-Down Exposure Metering

For lenses and other systems without automatic


When the automatic diaphragm ring does not couple with the

meter coupling lever of the camera, such as when using a
PC-Nikkor reflex mirror or bellows attachment, focusing should
be done with the lens wide open while exposure measurement

and shooting must be done with the lens stopped down.
In A mode;

Take the picture with the lens stopped down. With a PC-

Nikkor, correct exposure must be determined before
shifting the perspective. To do this, first use the AE Lock;

the lens can then be shifted to take the shot.

In M mode:

Stop down the lens to determine the correct exposure, then

take the picture.
