None (while you may find one, it will not perform as you may expect) !.!.!. polarizing filters are designed for lenses no wider than a 24 mm on a 35 mm camera!. Two reasons for this!. 1) when using a polarizing filter to darken the sky, the most darkening is at 90 degrees to the suns path !.!.!. none when parallel to its path!. 2) usually the reflections captured by super wide angle lenses are used in the images composition!.

You will have to write Tiffen, Hoya or B&W filter companies and see what they can do for you!.Www@QuestionHome@Com

B+W Slim Mount circular polarizer!. The Kaesemann MRC coated is $193!.18 at Adorama; the other model is $99!.70!.

You'll find similar prices from Heliopan, Singh-Ray, Hoya and Tiffen!.

Don't be upset by the price - I paid $99!.00 for a B+W 72mm Slim Mount circular polarizer about 5 years ago!.Www@QuestionHome@Com

You will definitely need a slim one!. I prefer Hoya to cut down on cost!. Using a polarizer with a wide angle is not a good idea, since the effect will vary along the width of the image!. One part of the sky will be darker blue than the rest and it will appear uneven!.Www@QuestionHome@Com
