Off Camera Direct and Bounce Flash
Cactus AF45 can be operated wirelessly with Cactus
Wireless Flash Trigger. Off camera flash provides better
lighting control of your subject by placing AF45 at various
angles and distances without being hindered by wire. The
flash can be aimed either directly at the subject or at many
different types of reflective surfaces such as ceilings, walls
or photo umbrellas and still maintain fully automatic
exposure control and manual control.
Power Zooming
Automatic Motor-zoom Control
If you use a zoom lens, it could transmit focal length
information to the camera. The camera will pass this
information to the flashgun. The flashgun then
automatically adjusts its zoom position to comply with the
focal length of the lens. Automatic motor zoom control is
only possible with cameras that allow digital data
transmission to the flashgun.
The LC display on the flashgun indicates zooming position
of 24-28-35-50-70-85mm. When the flashgun is first
switched on, the zoom position is set to 35mm. As soon as
the camera’s shutter is lightly touched, the focal length of
the flashgun is automatically adapted to the focal length of
the lens. If the flash head is at bounce or swivel position,
the zooming position of the flash will be adjusted to 50mm
and indicated in the LC display as auto mode 50mm.
