K&F Concept K-Series Pro 82mm Slim Circular Polarizing Filter Polarization Filter CPL Filter
For me a very good polarizing filter, use it on the Sigma 10-20mm 3.5 Ex for Nikon!! So far no reflections or loss of sharpness! Of course you lose 1-2 light levels because the filter glass is darker. But that's normal. Example photos: 1. 20mm with filter, 2. without filter, 3. 10mm with filter, you have to be careful because the full power of the lens is coming!! With a 10mm filter, always turn it back a bit, because the angle to the sun always causes barrel-shaped blue coloring! But not because of the filter! Is wide angle (physically) due, even with very expensive polarizing filters! Great value for money, of course!!, Use the filter in landscape photography!! Otherwise without!!
