Filters
• Nikon filters can be divided into three types: screw-in, slip-in,
and rear-interchange. Use Nikon filters; filters manufactured
by other makers may interfere with autofocus or electronic
range finding.
• The D3 can not be used with linear polarizing filters. Use the
C-PL circular polarizing filter instead.
• The NC and L37C filters are recommended for protecting the
lens.
• To prevent moiré, 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.
• Center-weighted metering is recommended with filters with
exposure factors (filter factors) over 1× (Y44, Y48, Y52, O56,
R60, X0, X1, C-PL, ND2S, ND4, ND4S, ND8, ND8S, ND400, A2,
A12, B2, B8, B12).
