The 16-48x/20-60x Zoom Fieldscope Eyepiece from Nikon is a nitrogen-filled fully multicoated zoom eyepiece ideal for bird watching, terrain navigation, and digiscoping. Place this eyepiece on your fieldscope to zoom the range of focal lengths. When attached to an EDG series fieldscope, magnify the focal length of your optics by 20x-60x.
