Focusing mechanism

The focusing mechanism is located at the top between the two barrels of the binocular and can be either a wheel or a toggle. This mechanism is used to adapt the focus when viewing an object. Some wheels/toggles/knobs adjust easily and some not that easily. Some binoculars, known as “auto focus binoculars”, “self¬†focusing binoculars”, “focus free binoculars” or “fixed focus binoculars”¬†have no central focusing knob/wheel; in their case the focus has been fixed at the factory.
