Filters very good reflections, but reflects total and reduces the image resolution

War itself with this filter very peace. Me a lot but on the images are slightly blurred with filters and act as a Matter without (Canon 450D - 18-135mm STM). So I switched to a Hoya HDFilter and did not regret the images are of the same detail as without the filter and the colors are vivid. That is why I would always recommend the brand filter, so rather spend a few more euros. Am not a professional but it bothers me if the quality suffers.

Who but a good filter effect for reducing reflections and searches may waive some details and color, which takes place with this filter a good price / performance.
