The Nikon Aculon A211 8×42 Binoculars are ideal for use for nature excursions and wildlife safaris. They come with BAK4 porro prisms and aspheric eco-glass elements made of arsenic-free material. The binoculars cover a field view of 420 ft at 1,000 yards with their 8× magnification. They also offer an apparent angle of view of 58°. The anti-reflection, multi-coated optics ensure a clear and bright view of the scene at hand. The minimum focus distance from which these binoculars can operate is 16 ft. A 12mm eye relief allows you to conveniently use these binoculars for a considerably long time at a stretch. The turn-and-slide twist-up eyecups offer a quick re-setting of the eye relief. The ergonomic sculpted rubber armoring of the binoculars facilitate a firm grip.
This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.
