Switching the

Focusing Range

A range switch lets you select a focusing range

of either 1.8 m/5.9 ft. to infinity or 6.5 m/21.3 ft.

to infinity, depending on shooting conditions.

This setting can reduce the actual autofocusing

time.

● Before switching the focusing range, turn the

focusing ring to select a focusing distance

somewhere within the desired range.

● If you do not set the lens to a focusing distance that

is within the selected focusing range, autofocusing

may stop when it reaches the range boundary. This

is not a fault. If it happens, press the shutter button

halfway down again.

The focusing ring always works, regardless of

the focus mode.

● After autofocusing in ONE SHOT AF mode, focus

manually by pressing the shutter button halfway and

turning the focusing ring.
