2 Mirror LockupN
Camera vibrations caused by the mirror's reflex action when the picture
is taken is called "mirror shock". Mirror lockup keeps the mirror up
before and during exposure to reduce blur caused by camera
vibrations. Useful when shooting close-ups (macro photography), using
a super telephoto lens, shooting at slow shutter speeds, etc.
