and Diane Porter and a team of Iowa birders tested 24 spotting scopes
for a review in the March, 2003, issue
of Bird Watcher's Digest. This account is part of that review.
62mm Kowa has excellent optical qualities. We looked at the angled
ED version, which incorporates fluorite glass elements in the objective
lens to reduce chromatic aberration.
The body is grey and tan, with a raised-line sight on the side
and with a decorative, thin red ring around the barrel near the
extensible sunshade. It comes in angled and straight-through designs;
lower-cost versions of both models are available without the fluorite
Although the Kowas eye relief of 22mm is good at 20x, the
eye relief is only 11mm at 60x, and so at 60x, a user who wears
glasses will see only the center of the field of view.
Eyepiece is purchased separately.
