The 52mm Slim Multicoated Circular Polarizer Filterfrom 52mm Slim Multicoated Circular Polarizer Filterreduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A polarizing filter arranges and filters this directionally polarized light perpendicularly to reflected light, allowing for the absorption of much of this light, resulting in a reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

This filter is constructed from optical glass for high resolution and color fidelity and has eight layers of nano-multicoating on each glass surface to prevent internal ghosting and reflections and optimize light transmission. The surface is also water resistant for easy cleaning and for use in inclement environments and locations. It features a slim, 5mm-wide aluminum alloy filter ring, so it can be used with ultra-wide-angle lenses without vignetting. The filter ring can be rotated to adjust the intensity of the polarization effect and has a 52mm front thread for adding additional filters, lens hoods, or other lens accessories.

Q: 4. I am interested in purchasing filters: polarized filter as well as a ND filter. There are so many to choose from - any suggestions?Hoya vs B&W ? What specifications should I compare? I am prepared to spend the extra money for the quality that best suits my current (beginner) and future needs. Camera Nikon D750 lens Nikkor 24-120.

A: I use both Hoya and B&W filters and are equally satisfied with them. Don't use polarizing filters for wide angle lenses.

Q: 5. How many stops of light transmission are lost by this filter?

A: The light lose on the B+W High-Transmission MRC-Nano Master Circular Polarizer Filter is 1-1.5 f/stops.

Q: 6. Where are these manufactured? How many stops do you lose? Is it indexed as you turn the circular polarizer so you can understand you're settings in some manner?

A: As per our records, the B+W High-Transmission MRC-Nano Master Circular Polarizer Filter is made in Germany. Please note that this information is subject to change at any time. While there are no index marks on the filter, it does reduce the light by approximately 1.5 stops.

Q: 7. What is the difference between this one and the Basic version for $106?

A: The B+W High-Transmission MRC-Nano Master Circular Polarizer Filter (82mm) has a superior optical quality and a coating to enhance the light and color transition through the glass.

Q: 8. Will this filter work with my Canon 16-35 f2.8L Mark 4 lens ?

A: You wrote mark 4 but there was only the Canon EF 16-35mm f/2.8L original and II and III versions. The III has an 82mm thread and will work with this Zeiss filer. All but the original version of this lens will work with this filter.
