The SB-600 manual is incorrect in some of its range

specifications. The above table is correct (though rounded

slightly in some places). For ISO 100, shift the aperture

numbers in the ISO 200 down by one row (i.e. the column

for ISO 100 would start with f/1.4). For ISO 3200, shift the

aperture numbers in the ISO 1600 column up by one row.

To Set Manual Flash

1. Activate the flash. If it's already in Standby, a partial

press of the shutter release activates it; otherwise,

press the power (ON/OFF) button on the SB-600 to

turn the flash ON.

2. Press the SB-600's Mode button until Ë appears on

3. Set the camera to Aperture-priority (A) or Manual (M)

exposure mode and set your aperture and shutter

speed, as usual.

4. Set the camera to Single Servo AF. While not

absolutely required, this generally makes the camera's

response more predictable.

5. Focus on your subject by pressing lightly on the

shutter release. Note the distance on the scale on the

6. Simply changing the aperture on the camera causes

the SB-600 to match it. Unfortunately, the SB-600

doesn't have a distance scale, so you'll have to use

aperture=GN/distance

exposure, and use the Guide Number tables below to

determine the GN.

With lenses that don't have CPUs (AI and AI-S), the

aperture on the camera isn't linked with the flash, so you

have to adjust flash power settings on the SB-600 to control

the flash output.
