Nikon C-PL405 Slip-In Circular Polarizing Filter

The C-PL405 is designed for specific Nikon super-telephoto lenses including the AF-S NIKKOR 180-400mm f/4E TC1.25 E FL ED VR, 500mm f/4E FL ED VR, 600mm f/4E FL ED VR, and 400mm f/2.8E FL ED VR.

You can adjust the polarizing effect by rotating the external wheel located on the filter itself after it has been inserted into the lens.

No, this filter is specifically designed as a slip-in filter for a select range of Nikon super-telephoto lenses and is not compatible with standard lenses or other filter types.

A circular polarizing filter reduces glare and reflections from non-metallic surfaces, enhances color saturation (especially blues and greens), and can improve contrast.

Use a soft, clean microfiber cloth to gently wipe the filter surface. Avoid using harsh chemicals or abrasive cleaners.

The filter size is 40.5 mm, referring to its diameter.

While designed to minimize impact, like any filter, it can subtly affect light transmission. However, its primary function is optical, and it's engineered to work seamlessly with Nikon's AF and metering systems.

Ensure you are using a compatible Nikon lens and that the filter is oriented correctly. Check the filter slot for any obstructions.

Verify that the filter is correctly inserted and that the external wheel is rotated to an effective polarizing position. The effect is dependent on the angle of light and the reflective surface.

Ensure the filter is clean. Re-check for proper seating in the lens. If issues persist, test without the filter to rule out other lens problems.
