8. Focusing

Fig. 10

Set the aperture to its maximum by pressing the aperture stop-

down button, and focus by rotating the focus ring.

Before shooting, press the aperture stop-down button again to

stop-down the aperture.

•

When using the Nikon D3 or D300 camera, you can take a picture

without operating the aperture stop-down button (the aperture can

be stopped down to a selected aperture automatically by pressing

the shutter release button without pressing the aperture stop-down

button). Alternatively, the aperture stop-down button can be used.

• While using tilting and/or shifting, the camera’s electronic range

finder cannot be used to confirm correct focusing. Focus should

be confirmed by checking the image in the camera's viewfinder.

•

When you change the degree of tilt and/or shift after focusing

the subject will become out of focus.

9. Depth of field

• Approximate depth of field can be

determined by checking the depth-of-

field scale.

•

Using the aperture stop-down button

of the lens or the camera’s depth of

field preview (stop-down) button (with

the D3 or D300 camera), the depth of

field can be observed while looking

through the camera viewfinder.

• For more information, see p. 222.
