Mirror-up Photography
Use this function to avoid any camera vibrations when using slow shutter speeds, telephoto lenses,
etc., where even the slightest camera vibration could result in a blurred image.

and exposure should be set before raising the mirror.
To further reduce the possibility of camera vibration, use a tripod and an electromagnetic or a mechanical
cable release.
