Quality filters!

After I - amateur filmmakers with professional ambitions - have long sought a good Vario ND filter, which can be computationally final price, I finally find anything; A filter absolutely good value for money.
ND Vario filters to the exposure time to keep not only in photos but especially when shooting with DSLRs constant imperative in bright light and an open aperture (eg 24fps = 1/50 30fps = 1/60 50fps = 1/100). I have also fixed filter tasted but these are the films not recommended because lighting conditions are constantly changing.

I have tested the filter in Haida videos and photos extensively. I was up to find himself with my wide angle lens (11mm to 1.6x crop) no vignetting around 90% of the density. From 4 / 5ths darken the edges slightly more strongly than the center of the picture, however, that seems to be a common behavior for all Vario filters in combination with a wide angle lens. The color neutrality is absolutely available. I could not detect any differences to the original photo.
The filter also can be adjusted very soft, but still retains the set position for hesitation. Moreover, in a very elegant and chic carton.

The only negative is that my 86mm lens cap is not properly clings to the filter. When in doubt, it is but on the cover that I was not able to test.

All in all I am very satisfied with the purchase and that's why there are 5 stars for an excellent filter and a nice and reliable Amazon partner!
