The Sigma 86mm Water Resistant UV Filteris a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. This filter is especially useful when photographing at high altitudes or around bodies of water. No additional coloration or contrast is provided, allowing you to pair this filter with others.

A UV filter is also useful as a general protective filter to leave on a lens at all times. This filter helps to reduce dust and moisture from reaching your front lens element and provides additional protection in case of drops or situations where scratching could occur.

This Sigma WR UV Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.

Q: 5. 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: 6. 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.

Q: 7. why am I having problems with scratches on the glasswhy am i getting scratches on the glass?

A: 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.
