The Olympus 8-16x25 Zoom PC I Binoculars: For Sightseeing and Spectator
Sport These Stylish and Compact Binos Score Big with a Powerful 16x Zoom
For when portability is as important as optical quality there is the
Olympus PC I series of binoculars; aimed at the urban dwelling sports
and sightseeing enthusiast, the 8-16x25 Zoom PC I features a sleek,
stylish design yet compact dimensions. While great as a general use pair
of binos, they excel when utilised for bird watching, if added to your
kit bag when camping and hiking, plus are superb for use at sports
events and when travelling.
These standard porro prism type binos feature a multi-coated lens for
maximum image brightness and contrast, high quality optics, plus the
added worry-free feature of UV (ultraviolet) protection. Added to the
mix are precisely ground prisms and lenses made of brightness-enhancing
barium crown glass (Bak-4) to ensure clarity and brightness to the very
edge of the field of view.
Peace of mind and years of pleasure are further guaranteed thanks to a
25-year European warranty.
This particular zoom model offers 8x to 16x magnification and a 25mm
objective lens diameter. As it sounds, up to 16x magnification produces
an image that appears as if the user were 16 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 ideal.
Also worth considering for low light work is the exit pupil. Here that
is 3.1 to 1.6 mm, which for 8x25 binoculars, for example, is arrived at
via 25 divided by 8 = 3.1 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, due to the zoom
capability, is 79-51 metres, and is defined as the width of the viewable
field at a distance of 1000m from the point of observation. Closest
focusing distance is five metres.
Offering an 8x to 16x zoom magnification to bring faraway points of

Fast and easy focusing is provided courtesy of a large, centrally placed
knob. The 8-16x25 Zoom PC I further sports a 15-12mm eye relief for
extra comfort, plus diopter adjustment for comfortable viewing without

field of view is 4.5° to 2.9° while the apparent angle of view is 36° to
