in order to fully benefit from a camera’s
Autofocus feature. Set your camera to
“Single Point-AF” and use the pad or
joystick to select the points from your
subject. DSLRs such as the Nikon D7000
or Canon EOS 7D have another useful
function: these SLRs are able to select
a group of points besides just a single
point. This makes it easier to sharply
map moving objects when they are not
exactly in the desired image section.
However, for entry level SLRs you should
select the middle focus field under
difficult light conditions as the only cross
sensor of the camera is located there.
Modern autofocus systems are, in
general, very reliable. You should adjust
the AF mode to your subject to always
get the perfect result. Use the single
image AF (Canon: “One Shot”, Nikon:
“AF-S”) for static subjects (persons
and objects). Moving subjects can be
captured best with “Servo-AF” (Nikon:
“AF-C”). Usually your camera focusses
as soon as you press the trigger halfway. But if your object is moving fast
then it is not easy to focus and shoot at
the same. In situations such as these it
is best to set the focus to another button
using the camera menu. Many models
have the option to assign the focusing to
the “AE Lock”- button at the back of the
camera. You can now adjust the focus
with your thumb and shoot with the
index finger.
