Title: Don't buy this for your digital slr
Review: I got this polarizer filter thinking it did the same thing as a circular polarizer but it's not the same. It's a LINEAR polarizer as opposed to a CIRCULAR polarizer. If you have a DSLR, get a CIRCULAR polarizer. A LINEAR polarizer won't be able to meter or autofocus correctly. I didn't know this when I bought it and it didn't say anything about it in the product description. It didn't work on my Nikon D7000, so I returned it.If you're shooting film, I'm sure this could be a nice filter.
