Canon EF 300mm f4L IS USM - Manual (Page 6)

ENG-5
To enable autofocus, set the
focus mode switch to AF. To
focus manually, set the focus
mode switch to MF and turn the
focusing ring.
One of two focusing distance
ranges can be set with the
focusing limiter switch: 1.5 m -
infinity or 3 m - infinity.
2. Setting the Focus
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.
