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 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, 
ND400, A2, A12, B2, B8, B12).

Water guards
• Water Guard WG-AS2: The optional WG-AS2 is a water guard 
that covers the base of SB-900 flash units mounted on the 
D300, increasing the SB-900’s splash resistance by 
protecting the accessory shoe contacts from rain and 
spray.
PC card 
adapters 
• EC-AD1 PC Card Adapter: The EC-AD1 PC card adapter allows 
Type I CompactFlash memory cards to be inserted in
