Whatever you buy, be aware that at very wide angles, the degree of polarisation of the sky varies across the field of view, and you will get variation in the blue shading across your image. This is not a fault of the filter - polarisation of sunlight from the sky is maximal at +/- 90 degrees from the sun, minimal at 0 / 180 degrees. At 15mm you have about 100 degree field of view, which includes the maximum and minimum effects. In some instances the resulting effect is very marked, so be careful. At 35mm you may not notice, but at 24 to 15mm you definitely will.

Thank you for the information.

I’m planning on getting this filter this week sometime.
