Product Description:
These filters are used by many photographers to protect the front element of their lens from abrasions, dust, and moisture. They also have a very subtle warming effect, which can be useful to counter the "cool" colors you sometimes get in bright sun or in shade. They're available in sizes to fit most EF lenses. TYPE: Screw-in

The Canon 72mm UV haze filter not only helps to protect your lens from dust, moisture and scratches, it also allows you to correct for UV effect and eliminate haze from your photos. This filter will absorb approximately 71 percent of UV rays, helping to eliminate haze's bluish cast that can obscure distant details. This filter easily screws onto your 72mm lenses.

This is a very good filter. I had a B+W filter that broke when a friend dropped my camera. I decided to try this Canon filter and I am impressed by its performance.
