Canon EF 180mm f3.5L Macro USM - Manual (Page 6)

ENG-5
You can set the focusing distance range to
0.48 m/1.6 ft. to infinity or 1.5 m/4.9 ft. to infinity.
By setting the suitable focusing distance range,
the actual autofocusing time can be shorter.
3. Switching the Focusing
Distance Range
If you autofocus outside the set focusing distance
range, the lens may stop focusing at the start of
the focusing range; however, this is not a
malfunction. Press the shutter release button
halfway again.
4. Hood
The ET-78 II hood can keep unwanted light out
of the lens, and also protects the front of the lens
from rain, snow, and dust.
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by the arrow to secure it.
The hood can be reverse-mounted on the lens
for storage.
• Part of the picture may be blocked if the hood is
not attached properly.
• When attaching or detaching the hood, grasp
the base of the hood to turn it. To prevent
deformation, do not grasp the rim of the hood to
turn it.
• Remove the hood when using the macro flash.
