EV RANGE OF THE CAMERA
The camera’s meter may be used only within the shutter
speed range covered by the exposure value (EV) range
of the meter, which varies with the aperture and ASA
setting.
The chart on page 37 shows the relationships between
the f-stop, shutter speed and film speed, indicating the
slowest functioning shutter speed (for metering pur
poses) with any film speed/f-stop combination.
Careful attention to the following instructions will as
sure precise exposure, automatically, over the complete
exposure control and meter range capability of your
Nikon EL2.
■ Auto exposure control at full aperture
For example, with an f/1.4 lens and ASA 100 film, the
automatic shutter will function down to one second
with the lens set at 1.4, and proportionately slower as
the aperture is closed.
Using a standard of ASA 25 film, you may be assured
of at least a four-second speed regardless of the aperture
of the lens used as long as the lens is set at full aperture
(refer to Table).
Using ASA 400 at f/1.4, the slowest speed is 1 /4 second;
however, as the aperture is closed, the functioning shut
ter speed becomes progressively slower until we reach
f/8 when the slowest speed of eight seconds is function
