•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.
•Magnifying Eyepiece DK-17M: The DK-17M magnifies the view through the viewfinder by approximately 1.2× for greater precision when framing.
•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-3right-angle viewing attachment to the D810.
•Antifog Finder Eyepiece DK-14/Antifog Finder Eyepiece DK-17A: These viewfinder eyepieces prevent fogging in humid or cold conditions.
•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).
