Setting the aperture

Calculate the aperture by using this equation and table. To ensure the correct

exposure, use an aperture smaller than the one obtained from the equation.

ISO sensitivity 25 50 100 200 400 800 1000

Coefficient (m/ft) 1.4/4.6 2/6.6 2/6.6 4/13 4/13 5.6/18 5.6/18

For example, at an ISO sensitivity of 100 with a subject 0.5 m (1.6 ft.) away and

the wide-flash adapter in place, the suggested aperture is:

Therefore, you should use at least f/4 or an even smaller aperture, such as

f/5.6 or f/8.

When shooting subjects closer than 0.6 m (2 ft.)

With the SB-600 attached to the camera, sufficient illumination of the subject

cannot be obtained. In this case, use the SB-600 off-camera by attaching the

optional TTL Remote Cord as shown below.

• In D

flash operation where Monitor Preflashes are fired, when the SB-600 is used

with D/G-type CPU lenses, you may not be able to get the correct exposure, because

distance information from the lens is used. In this case, position the camera (A) and the

SB-600 (B) at equal distances from the subject.

• For F5 cameras with the High-Magnification Finder DW-30 or DW-31, or F4 cameras with

the High-Magnification Finder DW-20 or DW-21, use the optional TTL Remote Cord

SC-24 instead of the SC-17.

f/stop ≥ 2 ÷ 0.5 = 4 (in meters)

f/stop ≥ 6.6 ÷ 1.6 = approx. 4 (in feet)

f/stop ≥ Coefficient ÷ Flash-to-subject distance

Use either the SC-29, SC-28 or SC-17.
