1 = 3D Matrix Metering is selected with D-type. AF Nikkor and Matrix Metering is selected with non-D-type lenses.

2 = With maximum aperture of f/5.6 or faster.

3 = Aperture cannot be selected.

4 = Set preset ring, then use AE-lock lever before shifting.

5 = Set preset ring, then determine exposure before shifting.

6 = Set shutter speed to 1/125 sec. or slower.

Because the Speedlight is relatively close to the lens, when a larger lens is used, or when a zoom lens is extended, the top of the lens may obstruct the Speedlight. Built-in Speedlight cannot be used with the following lenses in the conditions indicated.
