The Nikon DG-2 Eyepiece Magnifier can be used on many Nikon SLR cameras,
including digital SLRS, allowing users to view a magnified image of the center
of the camera's viewfinder. This can be very useful when photographing objects
with very fine detail or high magnification and little depth of field. This
magnifier applies a 2x enlargement to the central part of the camera's
viewfinder. The rest of the viewfinder is not visible - something like a
magnifier to observe the detail of focused area at the center. The DG-2 has a
hinged mounting so that it can easily be swung out of the way to view the
entire, unmagnified viewfinder image.
Note! Some cameras will require an optional Eyepiece Adapter Ring.
