the viewfinder. Focus can be adjusted automatically or manually (see “Focus Mode,” 
below). The user can also select the focus point for automatic or manual focus (

0 45) 

or use focus lock to focus to recompose photographs after focusing (

0 44).

Choose from the following focus modes. Note that AF-S and AF-C are available only in 
modes P, S, A, and M.

stationary, continuous-servo autofocus if subject is moving. Shutter can 
only be released if camera is able to focus.
