Urth 46mm Circular Polarising (CPL) and ND64 Lens Filter Plus+

It combines the benefits of a polarizing filter (reducing glare, enhancing colors) and a 6-stop neutral density filter (allowing for longer exposures in bright light) into a single unit.

This filter is for lenses with a 46mm filter thread. Look for the 'ø46mm' marking on your lens barrel or in its specifications.

While possible, stacking filters, especially with a slim-profile filter like this, can increase the risk of vignetting and light loss. It is generally recommended to use only the necessary filters.

The ND64 component reduces light by 6 f-stops.

It uses 20-layer nano-coated German SCHOTT glass, known for its high quality and excellent light transmission.

Yes, the filter features a rotating outer ring that allows you to adjust the degree of polarization to achieve your desired effect.

Urth offers a lifetime quality guarantee on this filter.

Ensure you are using the correct filter size (46mm) and that both the lens thread and filter thread are clean and free of debris. Do not force the filter; try re-aligning it.

Although designed with an ultra-slim rim, extreme wide-angle lenses might still exhibit slight vignetting. Try zooming in slightly or consider using a compatible wider lens without the filter if vignetting is severe.

Ensure the outer ring of the filter is rotated to the correct position. The CPL effect is most noticeable at certain angles relative to the light source. Experiment with rotation while viewing through the viewfinder or live view.

The 6-stop ND filter significantly reduces light. Adjust your exposure settings accordingly, or consider using a lower stop ND filter if this level of light reduction is too much for your intended shot.
