Power Zooming

• Automatic motor zoom control

If you are using a zoom lens, which transmit its focal length to the camera, the camera will pass on this information to the flashgun. The flashgun then automatically adjusts its zoom position to comply with the focal length of the lens. Automatic motor zooming reflector control is only possible with cameras permitting digital data transmission to the flalshgun.

The LC D display on the flashgun indicates zooming positions of 24-28-35-50-70-85mm. When the flashgun is switched on, the activated zoom position is set at 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.

Whenever the flash head is not at a normal position (facing to the front), such as in bounced or swiveled at different positions, the zoom position will be at 50mm as indicated by the LCD display with a brief flash in auto mode.
