The filter came with a sizeable embedded chunk of black gunk (looks like a large grain of black sand) deep in the glass of the filter and it is un-removable. Apparently, Tiffen needs to work on quality control[...]so I'll buy Hoya, with whom I've had nothing but excellent results.

This thing works very well. I enjoy shooting the horizon and this has come in handy a lot. I have used it a lot at sunset to campture the moon rising. It seems a little pricey for what it is, but it works great.
