Delivers Optical Perfection, Whether Day or Night This particular
model offers an 12x magnification and a 50mm objective lens
diameter. As it sounds, the 12x magnification produces an image
that appears as if the user were 12 times closer to their
subject, while the objective lens diameter refers to how much
light can be gathered to form that image. While for daytime use a
lens diameter of 21 to 25mm is useful, for night-time viewing
something between 35 to 50mm is recommended. Therefore the 50mm
specification here indicates excellent suitability for low light
visualisation. Also worth considering for low light work is the
exit pupil. Here that is 4.2mm, which for 12x50 binoculars is
arrived at via 50 divided by 12 = 4.2 exit pupil in mm, so beyond
the 2-3mm which is generally thought of as being suitable for
daylight use. Another thing to take into account is the field of
view, which here is a wide 80.3 metres, and is defined as the
width of the viewable field at a distance of 1000m from the point
of observation. Angle of view Click here for more info Versatile
and Bright, these Binos Will Have you Reaching for the Stars
Offering an 12x magnification to bring faraway points of interest
that much closer plus a 50mm objective lens diameter, the Olympus
12x50 EXPS I Binoculars incorporate fully multi coated lenses to
deliver maximum image brightness, visual impact and image
defining contrast. Fast and easy focusing is provided courtesy of
a large, centrally placed knob. What’s more the high index BaK-4
porro prisms naturally provide images that are crisp from edge to
edge, while built-in dioptric correction adjusts to individual
eye. The 12x50 EXPS I model further sports a long 18.3mm eye
for extra comfort, diopter adjustment for comfortable
viewing without glasses, and offers a near focus distance of six
metres. Prism types explained Click here for more info Engineered
