Introduction
In the history of human needs one of those most desired
has been to be able to magnify distant objects.
Let's think of the film Robin Hood with Mel Gibson
where Morgan Freeman gives him a primitive binocular
made out of two lenses held together by a leather
cylinder and Mel Gibson begins to wave his sword around
seeing his enemies apparently so close; of Hitchcock's
Window in the Courtyard where James Stuart uses the
tele-eyepiece of his camera, not having a binocular,
to first discover and then prevent the assassin's
moves in the apartment opposite, or of Gattopardo
by Visconti where Prince Salina´s studio was
full of sparkling telescopes and binoculars. To move
on to The Contact where a child Jodie Foster searches
for her mother amongst the stars with a binocular,
as well as many war films like The Battle of Midway,
where the adversary American naval officers and the
Japanese spend all day searching for each other through
binoculars in the ocean's liquid plains.
It's exactly here that Nikon comes into the picture,
precisely in 1917 when Admiral Mitsubishi of the imperial
Japanese Navy created the company, Nippon Kogaku (literally
translated ko=light, gaku= study, therefore "the
study of light") to supply precision optical
material for military use.
Therefore Nikon didn't start out as a photographic
factory but as one of binoculars and telescopes.
Tens of years have passed by and we get to today:
still today Nikon has as one of its strengths the
production of terrestrial binoculars and telescopes.
The Models

It's easy with a simple rotation of the two
FSA adapter disks to change instantly form horizontal
to vertical format

Nikon divides its production of telescopes
between the Spottingscope and the Fieldscope. The
first are for general use, telescopes that boast the
best price/performance ratio; the second are the state
of the art in optical vision by Nikon.
For this experience we have used the top of the Nikon
range, The Fieldscope 82mm ED. Thanks to the front
lens diameter of 82mm, this model boasts maximum light
to pupil giving better vision during the day, at sunset
and at night.
According to the interchangeable eyepiece that is
fixed to the Fieldscope there can be from 20x to 70x
magnifying; one can begin with a 20x lens, then to
30x and 38x (both WA) and also 50x, 50xWZ, 75x WA
up to 20x-45x zoom lenses and 25x-75x.
Thanks to their interchangeability one can begin to
work with a normal lens, like a 30x then later move
on to zoom lens and/or a strong magnifying lens.
A general rule of thumb translates the lens used into
the type of enlargement required, with a 75x lens
the same enlargement as a 7,500mm is obtained but
with incomparable quality of vision with respect to
that reached using a mirror and even with the most
noble reflex.

The UBK arm to fix any type of digital compact
camera to the Fieldscope, also without threaded
lens attachment: 1)Fieldscope 2) Tripod attachment
3) Spherical head with quick release attachment
4) Spherical head blocking arm 5) Fieldscope fine
tuning screw 6,7) fine tuning screws for horizontal
and vertical camera movements in the top left
the Fieldscope attachment blocking screws with
rotation marks |

It's possible to rotate the Fieldscope pushing
the release knob to go from direct vision to photographic
shot |

The FSA-L1 adapter to connect Nikon reflex digital
and non digital cameras; on the right hand side
the regulating screw is visible for the optical
FSA-L1 adapter for all Fieldscope types and the
screw to go from horizontal to vertical photographic
format |
| |
|
 |
The FSA-L1 adapter fixes onto the Fieldscope
instead of the lens. A wide threading range makes
it an all-in-one with the Fieldscope |
