Clearly recognizable improvements (see customer images - the two jets)

So the filter really pulls something out at the photograph of white or gray objects in the sky.
Recommended to me was the filter on Facebook from a so-called spotters, the so - like me - aircraft photographed in the sky.

I had previously used a pure UV filter from Hama, which unfortunately did not achieve the desired effect, after I had done this ordered me here. And the first attempts were already enormous! The effect is actually visible, as you can see at my two customer images above (SunExpress Boeing 737 and Airbus A330 Air Berlin).

One should note that a well be lost to two apertures through the additional lens. And you want to take pictures very distant points like small aircraft at 10km altitude, the small object is already slightly out of focus (when using a cranked 75-300mm lens). But made for close-ups like this from me this filter is highly recommended!

Oh ... one more thing to the reflections that have been raised here:
logical because there's reflections on the photo when shooting lights / candles directly and up close. But any normal photographer also know that this is the case for all of the filters and the most lenses.

No offense ... but that had to get out again! Their lousy rating because ignorance has now really do not deserve this filter!

Yes ... absolutely recommended! Thumbs up for this filter! The tip I got from a longtime spotter and looking forward, this now to pass =)
