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

cafeful 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.
