Camera’s exposure mode should be set to either A (aperture priority) mode*

, or M
(manual) mode*

In general close-up photography, the depth-of-eld*

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 ash operation in A or M mode with TTL metering (TTL
lamp on) is described.
e following instructions from the next page assume that you are using one of
the following cameras and macro lenses.
Camera: A camera with A (aperture priority) mode or M (manual) mode.
Lens: 50mm F2.8 Macro
100mm F2.8 Macro

exposure.

shutter speed that is slower than the camera’s sync speed.

focused. In close-up photography, this range is shallower and
the out-of-focus range is wider.
