Key Features
- 1.25 to 1.4x Filter Factor
- +0.3 to 0.5 Stops
- Helps to Eliminate Reflections and Glare
- Reduces Haze in Landscapes
The Sigma 105mm WR (Water Repellent) 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.

Will this work with a Lee Foundation Holder or a Cokin Z-Pro holder?
Unfortunately no, this filter will not work. Those filter systems require square or rectangular filters.

Real-life experience comparison regarding the 'water repellant' coating of this filter vs., say, the B + W circular pola? Any difference in environments with rain/snow/humidity? Thanks.
Yes, the water repellent works quite well when it comes cleaning the filter without leaving streaks,etc...,as well as not fogging up.

Is there any quality degradation on 150-600mm ...
Is there any quality degradation on 150-600mm lens, at focal lenghts beyond 200mm?
The Sigma 95mm WR (Water Repellent) Circular Polarizer Filter would have the same effect on the lens at all focal lengths. While adding any optic in front of the optical formula of your lens will have some amount of effect to your lens' image quality, the Sigma 95mm WR (Water Repellent) Circular Polarizer Filter is a high-quality filter, and the benefit of its circular polarizing performance in reducing glare/flare from non-metallic items, increasing contrast/saturation, and deepening the blue hue in the sky (depending on your orientation to the sun) would mitigate any minor negative degradation you would obtain from using the filter on your lens.

question
why am I having problems with scratches on the glasswhy am i getting scratches on the glass?
A filter like a lens is still glass and is sensitive to scratches like any other lens.Some filters are better than others. But a lens cap still needs to be used when using filter to protect it when you put it in a camera bag.
