The Sigma 62mm Water Repellent Protector Filteris a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect overall image quality while helping to prevent dust, scratches, moisture, and other elements from reaching or damaging your lens. This filter is multi-coated to eliminate internal ghosting and reflections. An anti-static coating serves to limit the accumulation of static electricity, making dust particles easier to remove or preventing them from adhering to the filter. Additionally, a water-repellent coating results in an improved beading effect when in contact with water, as well as oil, for greater cleaning efficiency while enhancing scratch resistance.

Sigma WR Protector filters are constructed from optical glass with a black rim. Set within an aluminum-alloy filter ring that is durable while remaining lightweight, the glass provides increased clarity as well as color fidelity while the black rim further ensures that reflections do not occur along the filter's edge.

Q: 8. i have bought a sigma 77 mm polarized circular filter . I returned the first one after 3 days as I found small scratches on the glass and have now found considerable more scratches on the second after only three months prompting me to think that the quality of the glass or polarizing finish is not up to par . I am finicky about how and what I clean my filter with , and how I store my camera , so I know that what ever has caused the scratches can not be that significant , but maybe the glass is not as hard / strong as it should be. Can,t seem to find any specs on the grade or hardness of the glass used for these filters. Any body have any ideas ?

Q: 10. What is the light transmission of this?

A: Sigma does not have any published specifications for light transmission of this CPL (which I believe is typical because most CPLs have filter factors in a range) but does advertise a 30% increased transmission over their competitors' CPLs. This filter does have a 0.3-0.5 stop reduction of light, which equates to a theoretical numerical transmission of 81.2% (at 0.3 stops) to 70.7% (at 0.5 stops), the formula being 100% multiplied by half to the power of 0.3 and 0.5.
