The flash shooting distance range with zoom lenses having a variable aperture
With zoom lenses having a variable aperture, take note of the following before
setting the aperture on the SB-80DX and confirming the flash shooting distance
range.
Lenses having a variable aperture
m There are two maximum aperture values indicated in the lens model name.
For example with the AF Zoom-Nikkor 28-105mm f/3.5-4.5D IF, the maximum
aperture at 28mm is f/3.5, but decreases to f/4.5 at 105mm.
lReading the aperture on the camera’s LCD panel or in
the viewfinder
m After composing the picture by zooming in or out, read the aperture on the
camera’s LCD panel or in the viewfinder. Then set the same aperture on the
SB-80DX’s LCD panel and confirm the flash shooting distance range.
nAperture values are automatically compensated by the camera and appear on the
camera’s LCD panel or in the viewfinder. The aperture value displayed in the aperture-
direct-readout scale as seen in the viewfinder of the Nikon F5 or other cameras is fixed
and not automatically compensated.
lReading the aperture using the scale on the lens
m After zooming in or out to select the appropriate composition, read the
aperture using the aperture scale on the lens. Then set the same aperture on
the SB-80DX’s LCD panel and confirm the flash shooting distance range.
At wideangle zoom settings, read the aperture value at the green index (or line).
At telephoto settings, read the aperture value at the yellow index (or dot).
At intermediate settings, read the aperture value between the two indexes.
lReading the aperture using the camera’s aperture dial
F-401x/N5005, F-401s/N4004s, F-401/N4004 camera + CPU lens
m After zooming in/out to select the desired composition, read the aperture
using the camera’s aperture dial. Then set the same aperture on the
SB-80DX’s LCD panel and confirm the flash shooting distance range.
nSet the camera’s exposure mode to Aperture-Priority Auto (A) or Manual (M). The
aperture value set on the lens cannot be confirmed in the Programmed Auto (P) or
Shutter-Priority Auto (S) exposure mode.
nFor cameras having TTL metering, the aperture on zoom lenses is automatically
compensated by the camera.
nIn case of setting a larger or smaller value than the lens aperture on the camera’s aperture
dial, set the lens’ maximum or minimum aperture on the SB-80DX.
