Fieldscope ED 78mm
78mm Fieldscope rated highly with our judges for sturdy, intelligent
construction. You'll never fumble for the focus ring. Nearly as
broad as your hand, it extends all the way around the scope. It
turns smoothly and offers just-right resistance.
there is no sighting device or built-in sunshade, and the scope
is not waterproof. Birders who wear glasses may find the
eye relief of the 25-56x zoom not quite sufficient, so it's a good
idea to try it before you buy it.
scope comes in angled as well as the straight-through version we
tested. Both models use Nikon's ED (Extra-low Dispersion) glass.
Eyepieces are sold separately.
we tested the Fieldscope's optical resolution, using the 25-75x
zoom eyepiece Nikon sent us, we dialed the magnification back to
60x in order to compare the scope to those with 20-60x zooms. The
Fieldscope won the same outstanding score of 19 at 60x as the Swarovski
ATS80 HD and Leica APO-Televid 77. Interestingly, increasing the
Fieldscope zoom's magnification from 60x to 75x did not improve
Nikon Fieldscope lacks the superb engineering of its smaller sibling
(Nikon 60mm ED Angle Fieldscope
III). A Nikon representative told us (in January, 2003) that
Nikon will be bringing out a new, waterproof full-sized Fieldscope
within a year. Might
be worth waiting for.
