Basic flash modes (A mode/M mode)
Camera’s exposure mode should be set to either A (aperture priority) mode*
, or M
In general close-up photography, the depth-of-field*
must be quite shallow,
which usually requires a smaller aperture when shooting. It is therefore better to
select A or M mode, which enable you to select the aperture.
Using a macro lens is also recommended.
In this section, the basic flash operation in A or M mode with TTL metering (TTL

You can select both aperture and shutter speed. You can select a

the out-of-focus range is wider.
