The filter works really great. I had him for four days of intensive in changing Lichtverhältinssen on a Nikon D80 in use. Only at night, when was very little light enters the camera not perform manual white balance using the filters, without a filter but also not. Because I use different lenses and have these partially different diameters, I bought the filter for the largest objective lens diameter. I have the filter is not used as a protective cover, and unfortunately lost after four days. Spare I first ordered not because I came to my attention that even matte plastic lid of Erdußdosen etc. appropriate - first attempts were successful, but I have not tested enough to finally recommended that as an alternative. The Kaiser filter has anyway the advantage that a very similar "color" created by the many small prisms in the filter at all points of the sensor, while the can lid in various regions of different colors aufweißt, just a blurred image which is what about to see , Usually, this should also be normalized by the camera when the entire sensor surface is used for white balance.
