Nikon EDG Fieldscopes
EDG Fieldscopes are Nikon's top of the line spotting scopes. EDG Fieldscopes feature Extra-low Dispersion Glass (EDG) objective lenses with a 20-60x zoom eyepiece (85-mm size) or a 16-48x zoom eyepiece (65-mm size). The advanced VR versions feature built-in vibration reduction (image stabilization) pioneered in Nikon's cameras. The VR is very useful when viewing in the wind or digiscoping.
