Focus Lock
Focus lock can be used to change the composition after focusing,
making
it possible to focus on a subject that will not be in a focus
point in the final composition. It can also be used when the
autofocus system
is unable to focus (pg. 80).

button is pressed halfway will lock both focus and exposure
(an AE-L icon appears in the viewfinder when exposure is
locked; see page 126).
