Nikon D300 User Manual (en)

• 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 D300 can not be used with linear polarizing filters. 
Use the C-PL circular polarizing filter instead.
• Use NC and L37C filters to protect 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,
