EV RANGE OF THE CAMERA-continued
• How to read the EV range chart
The chart indicates the EV (for ASA 100) vs. shutter
speed range.
To determine the shutter speed range, note that the bars
in section A indicate the responsive range of the EL2's
photosensitive SPD element
(i.e.,
f/8 covers EV 6 ~ 23,
f/16 covers EV 8 ~ 23) for the f-stop in use.
In Section B, note the f-stop being used on the appro-
priate ASA scale. For example, at ASA 25 with the lens
set at f/8, we follow the line diagonally and find that it
intersects EV 5 at eight seconds, and at EV 18 runs off
the scale at
1/1000
second. ASA 100 at f/8 runs from
EV 3 at eight seconds to EV 16 at
1/1000
second.
In any
case,
it is generally the low end which requires a
careful check. The wide exposure (EV) range of the
Nikon EL2 will
encompass
most lighting situations.
It is only under dim-light or rare bright-light situations
that any
special
attention need
be
paid.
Full-aperture metering
The metering range is determined by the bars (Section
A),
f/number range in appropriate ASA scale (Section
B) and shutter speed (8 ~
1/1000
sec, Section C). For
example, the area encompassed by the heavy lines dem-
onstrates a combination of an f/1.4 lens and ASA 100
film.
Stop-down metering
The metering range is determined by the bars (Section
A),
f/number in appropriate ASA scale (Section B)
which corresponds to the stopped-down aperture in
operation,
and shutter speed (8 —1/1000 sec, Section
C).
The broken line demonstrates stop-down measure-
ment in the case of an f/8 lens combined with ASA
100
film,
indicating a range from
1
sec. to
1
/1000 sec.
