Adjusting the Zoom-Head Position

The SB-50DX has four zoom-

head positions: 24mm, 28mm

35mm and 50mm. When the

wide-flash adapter is used, the

zoom-head position is fixed to

14mm.

When a camera body that is compatible with

Digital Data Communication is attached to

the SB-50DX and a CPU lens is used, the

Power Zoom function activates and the

zoom head is automatically adjusted.

• When the lens focal length is not 24mm, 28mm,

35mm or 50mm, the zoom head adjusts to the

closest wideangle setting of the lens in use. (See

table below).

• When M is not displayed in the LCD panel, the

Power Zoom function is activated. If M is

displayed, press the ZOOM button a number of

times so M disappears from the LCD panel.

• To change the automatically adjusted zoom-head position, set the zoom-head

position manually. (See next page).

• When the wide-flash adapter is attached or when the flash head is tilted

up/down, the Power Zoom function becomes inactive.

The guide number varies according to the zoom-head position (p. 33).

Digital Data Communication

When the SB-50DX is used with cameras in Groups I and II (p. 28) or Nikon

digital SLR cameras, Digital Data Communication is performed. With a CPU

lens, the camera automatically sends lens information (focal length, etc.) to the

SB-50DX.

• Setting the zoom-head position manually

• To change the zoom-head position without

using the Power Zoom function or when the

camera/lens combination is incompatible with

the Power Zoom function, press the ZOOM

button to set zoom-head position manually.

• The zoom-head position changes in four

positions—24mm, 28mm, 35mm and 50mm

every time you press the ZOOM button. (Fixed

at 14mm with the wide-flash adapter.)

If the camera/lens combination is compatible with

the Power Zoom function, pressing the ZOOM

button at the 50mm position activates the Power

Zoom function. Pressing the ZOOM button again

sets the zoom-head position to 24mm.

• When the zoom-head position is set manually,

"M" appears above the "ZOOM" indication in

the LCD panel.

• Generally, set the zoom-head position to the focal length of the lens in use or

to the closest wideangle setting of the lens in use (see the table on p. 16).

• Wide-flash adapter

• With 14mm to 23mm lens, use the built-in

wide-flash adapter.

• Slide out the wide-flash adapter from the

bottom of the flash head, then attach it in front

of the flash head. The Power Zoom function

becomes inactive, zoom-head position is

automatically set at 14mm, and "ZOOM14mm"

is indicated in the LCD panel.

• To store the wide-flash adapter, detach it from

the flash head, then slide it back all the way

into its original position.

• When using a 14mm lens, the distance

between the camera and subject becomes increasingly pronounced from the

center of the frame to the periphery, so the peripheral area might not be

sufficiently lit in some cases.

Zoom-head position in bounce-flash or close-up photography

In bounce-flash photography (p. 40) or close-up photography (p. 43), the zoom-

head position is fixed at 50mm with the flash head tilted up and at 24mm with

the flash head tilted down. However, when the wide-flash adapter is used, the

zoom-head position is fixed at 14mm regardless of flash head direction.
