3. Taking Closeup Shots in the Manual Focusing (MF) Mode
When using this lens, shots taken with the
camera's manual focusing (MF) mode within a
range of less than 20 mm from the wide end
make the subject seem closer and larger than
with the autofocus (AF) mode.
The focusing distance ranges of the wide end
are shown below.
• AF in-focus range: 0.28 m/0.92 ft. to ∞
• MF in-focus range: 0.128 m/0.42 ft. to ∞
Focusing within a range of 0.128 m / 0.42 ft. to
less than 0.28 m / 0.92 ft. is possible only when
using the MF mode. (MF-only range)
The [MF in-focus range] will differ in accordance
z
with the focal length within a range of less than
20 mm from the wide end.
Refer to the specifications on page 16 for details

on the range of focusing distances apart from
