Mode

3. Switching the

Focusing Distance
Range

• Before switching the focusing

distance range from 1.5 m -

infinity to 3 m - infinity, first

turn the focusing ring so that

the distance scale index is

within 3 m - infinity.

• If the distance scale index is

within 1.5 - 3 m and the

focusing limiter switch is set

to 3 m - infinity, initial

autofocusing may cause the

lens to first stop at 3 m on the

distance scale. This is not a

malfunction. If this occurs,

press the shutter button again

to resume normal

autofocusing.
