•DK-14 and DK-17A Antifog Finder Eyepieces: These viewfinder eyepieces prevent fogging in humid or cold conditions. The DK-17A is equipped with a safety lock.

•DR-5 and DR-4 Right-Angle Viewing Attachments: The DR-5 and

Viewfinder DR-4 attach to the viewfinder eyepiece at a right angle,

eyepiece	allowing the image in the viewfinder to be viewed from
accessories	above when the camera is in the horizontal shooting
	position. The DR-5 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).
	• Nikon filters can be divided into three types: screw-on,
	slip-in, and rear-interchange. Use Nikon filters; filters
	manufactured by other makers may interfere with
	autofocus or electronic range finding.
	• The D3S can not be used with linear polarizing filters. Use
	the C-PL circular polarizing filter instead.
	• Use NC filters to protect the lens.
Filters	• To prevent ghosting, use of a filter is not recommended
	when the subject is framed against a bright light, or when
	a bright light source is in the frame.
