• Rubber Eyecup DK-19: The DK-19 makes the image in the
viewfinder easier to see, preventing eye fatigue.
• Diopter-Adjustment Viewfinder Lens DK-17C: To accommodate
individual differences in vision, viewfinder lenses are
available with diopters of –3, –2, 0, +1, and +2 m
–1 . Use
diopter adjustment lenses only if the desired focus can
not be achieved with the built-in diopter adjustment
control (–3 to +1 m
–1 ). Test diopter adjustment lenses
before purchase to ensure that the desired focus can be
achieved. The DK-17C is equipped with a safety lock.
• Magnifying Eyepiece DK-17M: The DK-17M magnifies the view
through the viewfinder by approximately 1.2 × for greater
precision when framing. The DK-17M is equipped with a
safety lock.
• Eyepiece Magnifier DG-2: The DG-2 magnifies the scene at the
center of the viewfinder for more accurate focus. DK-18
eyepiece adapter (available separately) required.
• Eyepiece Adapter DK-18: The DK-18 is used when attaching
the DG-2 magnifier or DR-3 right-angle viewing
attachment to the D4.
• Antifog Finder Eyepiece DK-14/Antifog Finder Eyepiece DK-17A:
These viewfinder eyepieces prevent fogging in humid or
cold conditions. The DK-17A is equipped with a safety
lock.
• Right-Angle Viewing Attachment DR-5/Right-Angle Viewing
Attachment DR-4 : The DR-5 and DR-4 attach to the
viewfinder eyepiece at a right angle, allowing the image in
the viewfinder to be viewed from above when the camera
is in the horizontal shooting position. The DR-5 supports
diopter adjustment and can also magnify the view
through the viewfinder by 2 × for greater precision when
framing (note that the edges of the frame will not be
visible when the view is magnified).
