Good square filter
Excellent packaging and high quality finish. I returned it anyway because the filter glass is dyed through. This results in vignetting in wide-angle shots, since oblique rays of light have to pass through a thicker filter layer than straight rays of light. You can see that by just looking through it with your eyes. There is no vignetting with surface-evaporated filters because the glass body remains clear on the inside. Unfortunately these are more expensive...
