Hello everybody! I just can strongly guided by the reviews here when choosing my pole filter and I have to say I was not at all disappointed. Use the filters on my Nikon D90 and have to say that one can conjure up really good pictures from the camera to the part especially in the summer. Rich blue in the sky and more vivid colors generally pep pictures on really. In the pictures here on Amazon, you can see the comparison with and without filter (unedited, shot with Nikon D90), which probably is worth a thousand words.
The only thing that is a little fummlig, the operation of the filter. But that's more the lens hood owed that way, I can easily screw yet, even if the polarizing filter is turned up. Therefore, no deduction for the filter. With a bit of skill to make it after a few tries with attached lens hood filter for the desired effect without turning the lens to become dirty with finger :)
