Using the integrated wide-angle diffuser / telephoto

lens cover

The wide-angle diffuser and the telephoto lens cover

change the beam angle of the flash unit. The wide-angle

diffuser enlarges it so that shots with focal lengths up to

24mm

are also illuminated uniformly.

This requires a reduction of the guide number and hen-

ce the range as well. By contrast, the telephoto lens

cover bundles the light cone for focal lengths of 85mm

and more, increases the guide number and hence

increases the range.

Wide-angle diffuser

When not in use, the integrated wide-angle diffuser

is pushed into the body of the flash unit below the

reflector cover.

• Pull the diffuser vertically out of the flash body and

allow it to fold onto the reflector cover of the flash

unit.

The diffuser is held in position by spring force.

• To remove it, proceed in the reverse order.

Telephoto lens cover

• Place on the reflector cover of the flash unit so that the

lens cover snaps into place.

• Pull to remove.

6.3 Flash exposure memory FE

Several Nikon, Sony and Canon cameras have a flash

exposure memory (FV memory).

This is supported by the flash unit in the Nikon i-TTL and

i-TTL-BL and in the Canon E-TTL flash modes.

It can be used to define and store the exposure level for

the subsequent shot before the shot is actually taken.

This can be useful when, for example, the flash

exposure has to be adjusted to specific details that may

not be necessarily be identical with the main subject.

This function is activated on the camera. The subject

details for the flash exposure are measured and brought

into focus by the cameraís AF sensor/metering window.

Pressing the camera’s AE-L/AF-L button (Nikon) or FE

button (Canon; the description may vary from camera to

camera; see the camera operating manual) causes the

flash unit to fire a test flash.

The stored metering value, for example “EL” or “FEL”,

is then displayed in the camera viewfinder.
