The shortest or minimum focusing distance
of binoculars is the minimum distance that you have to
stand from the object in order to focus properly on it. This
may be unimportant to the sailor who scans the horizon of the sea
but it is vitally important to the nature lover who scours the
environment in search of insects.
To give you some idea, the minimum focusing distance of various binoculars ranges between 1 and 8 metres.
