Canon EF 200mm f2.8L II USM - Manual (Page 6)

ENG-5
The following applies to the EF 135 mm f/2L USM, EF 200 mm
f/2.8L II USM, and EF 400 mm f/5.6L USM lense:
• 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 following applies to the EF 200 mm f/2.8L II USM, EF 300
mm f/4L USM, and EF 400 mm f/5.6L USM lenses:
• If the tripod mount covers the focusing limiter switch, it may be difficult
to operate the switch. In such a case, loosen the tripod mount's lock
nut and turn the camera so that the switch is clear.
The depth of field is the zone of
acceptable focus in front of and
behind the point of optimum
focus.
EOS cameras equipped with
the depth-of-field preview
feature allow you to see this
zone of sharp focus in the
viewfinder. The depth-of-field
scale is an approximate guide.
