I agree with the previous review only. That although only a couple of pictures taken with the polarizing filter, but here was a significant improvement in colors / contrasts seen (see example photos). This such a great effect I did not expect. The example photo without polarization filter shows what has so often bothered me at photos. Even when the sun shines dull colors and little contrast. Now I can eliminate exactly with the filter. Although the lens is already taken a lot of light when the filter corresponding to a high filter effect is set (see caption). But in most applications - nice weather - falls in my opinion, not so in's weight.
The quality of the filter is very good. Also, placing and rotating are not a problem (of course more difficult with the hood). All this can be expected at this price also. But I find it a bit unfortunate in the high price that the sleeve and lid are very poorly executed.
I can so far only recommend this filter. Dear immediately buy a good quality.
