3D Multi-Sensor Balanced Fill-Flash for Digital SLR: Speedlight emits series
of near ly in vis i ble prefl ashes (mon i tor pre fl ash es) immediately before main
fl ash. Pre fl ash es re fl ect ed from objects in all areas of frame are picked up
by fi ve-segment TTL fl ash control sensor and an a lyzed in combination with
range information from lens to adjust fl ash output for natural balance be-
tween main subject and ambient background lighting. Not avail able when
spot me ter ing is used.
Type
G or D

me ter ing is used.
