Negative Positive
Title: Not compatible with my Canon lens
Review: I'm sure this filter is a great purchase for the money for other lenses. However, when I attached it to my Canon 17-85mm, the Tiffen filter touched the lens glass. Bummer. Wasn't sure what to rate it as I wasn't able to see it's capabilities as a filter, but I wanted to make sure other buyers with my particular Canon lens were aware that this filter is not the right choice. Amazon was great with the return.
