• 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.
