Description
Flash control
i-TTL Balanced Fill-Flash for Digital SLR is selected automatically in all
modes except mode M or when spot metering is selected in modes
P, S, and A. Speedlight emits series of nearly invisible prefl ashes
(monitor prefl ashes) immediately before main fl ash. Prefl ashes
refl ected from objects in all areas of frame are picked up by 1,005-
pixel RGB sensor and are analyzed in combination with information
from matrix metering system to adjust fl ash output for natural
balance between main subject and ambient background lighting.
If type G or D lens is used, distance information is included when
calculating fl ash output.
