Subjects Not Suitable for Autofocus
Autofocus may not work well in the following instances, and manual focus
will probably give you better results:
Shiny subjects or Horizontally striped
subjects that reflect light subjects

in viewfinder/
different distances
rSk
eiueC-v
Rapidly moving subjects Slanted subjects
Subjects behind glass
(windows with water or
dirt on them)
Dark subjects
Night View
______ L
Subjects with little or no
contrast (a white wall,
for example)
Macro recording or
when shooting using a
tele-converter or wide
converter
Notes:
• Do not touch focusing ring during autofocus.
• Shooting subjects at a distance of less than 1 metre while using autofocus may result in poor picture quality. Be
sure to use adequate lighting in this situation.
• Under the following conditions it will take longer for autofocusing;
— When you are focused on a subject further than 1.2 metres, and quickly change to focus on a subject within
the tele-macro range (0.6—1.2 metres).
— When you are focused on a subject within the tele-macro range (0.6—1.2 metres), and quickly change to
focus on a subject at a further distance.
— When shooting rapidly moving subjects within the tele-macro range (0.6—1.2 metres).
• When the focused subject only occupies a small area within the autofocus zone, autofocusing may take longer.
Change framing so the subject occupies a larger area within the autofocus zone.
