En_icons Many photographers think of using a flash only at night or in poor lighting. However, a flash can be very useful in daylight too. Eliminate the shade under trees. Use fill-in lighting to sharpen the subject. Address catchlight in the eyes, and stop motion. Emphasize the lighting contrast. Enjoy more opportunities to use your flash.

PanelThe flash beam covers the frame from 14mm (with a wide angle diffuser built-in) to 70mm of the digital lens.(*) For a longer lens, the flash head reflector position stays at 70mm.
It turns 90 degrees upward and 270 degrees horizontally for bounce lighting.

BounceThe flash head also stores a small reflection panel for fill-in shots.
