Nikon Fieldscope ED 13-40×50 A Product description
-
ED Glass Elements: The Extra-low Dispersion (ED) glass incorporated in this Fieldscope suppresses chromatic aberration, a common optical flaw that can cause color fringing. This ensures remarkably clear, sharp, and true-to-life images across the entire zoom range.
-
Angled Viewing Design: The 45-degree angled eyepiece provides a comfortable viewing posture, making it ideal for extended observations, especially from a seated position or for sharing the view with others. It minimizes neck strain and allows for easy height adjustments for multiple users without moving the tripod.
-
Compact and Lightweight: Engineered for ultimate portability, the Nikon Fieldscope ED 13-40×50 A is incredibly compact and lightweight, making it a perfect companion for birding, hiking, or travel where space and weight are critical considerations for your gear.
-
Fully Multilayer-Coated Lenses: All lenses and prism surfaces are fully multilayer-coated, optimizing light transmission and eliminating flare. This results in bright, vividly rendered images with superb contrast and color accuracy, even in challenging lighting conditions.
