I was so surprised at how bad this filter is. I had it on while taking some night photos and it crated so many ghosts (I bought two, one for each of the lenses I was shooting) and it completely ruined just about ever shot I took. I'll never get those shots back and it was a rare opportunity to boot at that location. Splurge a bit and buy the more expensive variants.
