Nikon 1683, FM2 Body only instruction manual Stop-down exposure measurement

Stop-down exposure measurement

This exposure measurement method is used when the dia- phragm on the lens does not link with the meter coupling lever on the camera body, such as when a non-AI lens or an exten- sion ring is mounted on the camera. The procedure is as follows:

1)Set the ASA/ISO number.

2)Compose your picture and·secure subject focus .

3)Press the shutter release button lightly to turn the meter on.

4)Perform exposure measurement, depending on the type of lens used:

•Lens with automatic diaphragm

Determine the correct exposure while pressi ng the depth- of-field preview lever ® , then take your finger off the lever and depress the shutter release button .

•Lens without automatic diaphragm (PC -Nikkor lens)

First, determine the correct exposure by adjusting the shutter speed and aperture. Then, focus at full aperture. Shift the lens so that you get the desired composition. Re- turn the aperture setting to the preset position and shoot.

•Lens with fixed aperture (Reflex -Nikkor lens)

Exposure cannot be changed according to the aperture be- cause in this type of lens, the aperture is fixed. Determine the correct exposure by turning the shutter speed dial. If correct exposure is unobtainable, use an ND (neutral den - sity) filter or change the illumination to adjust the exposure .
