The Minolta focuses the image based on a small rectangle in the center
of the viewfinder.  When you hold the shutter release halfway down,
it holds the current focus.  Therefore, you center the mountain, half
press the shutter, and after the camera focuses (about 1 second) you
may then recompose the picture.  There is also a button where your
right thumb rests which holds the exposure and aperture so you can
recompose to include, say, a bright sky when you want the exposure
correct for the landscape.
