TOP - sometimes better than "no"

After I made comparison shots with filters of Hama, Tamron and without with different focal length / aperture settings, is clear: this filter is the best and is depending on the light partially sharper contours than "no". Have compared a series high magnification of the photo. Also outlines the haze come partly. Better with this filter through while it blurred participated Tamronfiltern, with Hama little better, but not nearly well and top with B + W. The price difference is noticeable.

In addition, I realized that with this filter over "without" any change in brightness such as under Program AE occurred, WHILE changed with the cheap the behavior of the camera settings.

So 5+ points.
