The Rodenstock 67mm HR Digital Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

To prevent internal ghosting and reflections, multiple layers of anti-reflection coating are included. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters. The coatings associated with HR Digital filters results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

This filter is constructed from optical glass for increased optical clarity and color fidelity. Before being set within a thin brass filter ring that minimizes the potential for vignetting while enhancing durability and jamming prevention, the sides of its glass are blackened to help further eliminate internal ghosting and reflections from occurring along the filter's edge.

Q: 7. When using this polarizing filter on my D7100 with 18-105 or my 70-200 lenses and with a UV filter you rotate it and then can see the affect in the viewfinder from light to near dark. What should it be rotated to ? ie what result is achieved?Also, with the lens hood on it is difficult to rotate the filter but I assume I am to rotate it for the desired affect to be achieved? Or does this camera automatically adjust for the filter?

A: You rotate a circular polarizer to achieve a bluer sky or to cut glare from reflective surfaces. The camera will not automatically adjust for the filter, since this is a totally mechanical action. You should rotate the filter until the effect you are looking for has been achieved.

Q: 8. will this fit on my Nikkor 17-55mm 1:2.8 G ED Lens?
