Power Flash Grip 300
By using the Power Flash Grip 300, you are always
ready for problem-free flash photography. With the
flash reflector up, the unit will fire automatically
only when natural light requires a shutter speed of
1/100 sec. or slower. The shutter speed will be set
at 1/100 sec. in this case, and the aperture deter-
mined by the AF CPU on the basis of the absolute
distance of the subject (Flashmatic method), as
illustrated by the dotted line in the chart.
