I use the polarizer with a Nikon Coolpix P7700. The filter can be properly in the 40.5 mm internally threaded screw the lens and then sitting (apart from the intended movement of the lens barrel from) thanks to the good processing pleasantly firm. In addition, the polarization filter has itself on a 40.5 mm internal thread, into which I einschraube the lightweight hood JJC LH-CP17, so that the polarization filter between the lens of the P7700 and the Gegenlichblende sitting. In this way, all of the optical elements (lens, polarizing filters) are protected from stray light and the polarizing filter can be easily changed by rotating the lens hood. I was afraid it would come by screwing the lens hood on the polarization filter for vignetting / vignetting at maximum wide-angle position, fortunately this has not come true, it comes with me to no vignetting / vignetting (verified by photos associated with this lens hood bright wall with polarization filter with and without Geli (comparison of RAW images)). The polarizing filter does what you just by a polarizing filter when used correctly expected (disturbing reflections or reflections eliminate, enhance the blue sky, etc ...), a recognizable deterioration of image quality (checked at ISO 80) I could use in the filter does not recognize. In short: good product for a fair price!
