The Fieldscope 82mm ED is Nikon's flagship model for serious birders. They've pulled out all the stops to make a full-throttle scope that's easily handled and thinks nothing of impending weather conditions. Extra-low dispersion glass gives nearly perfect color focus upon a single plane, and with contrasty, intricate or glare-filled situations you can genuinely observe the difference.
It is entirely a matter of personal preference, and no one can say definitively whether you will prefer a straight or angled scope until you experience them both. But common wisdom says that straight scopes are easier to initially locate your subject, as well as being a bit shorter, lighter and less expensive to manufacture.
Amongst the very short list of Japanese-made ultrapremium spotting scopes, the Nikon 82 ED Fieldscope arrives to you with the Vue-Thru case. This valuable accessory is quite nearly a necessity, and is not included but rather an expensive additional option with the European-made ultrapremium units.
All of Nikon's spotting scope line is backed up by the "No-Fault" lifetime warranty. Regardless of what happens to your scope-even of your own negligence-Nikon will repair or replace (at their option) your scope for just $10 plus the return shipping costs.
