- One should be careful at the 20mm end of the range: My (Pentax) 20/2.8
- takes 67mm filters, and my impression is that there is not much room
- wasted near the corners. Some polarizers are significantly thicker than
- regular filters and could cause vignetting when the filter diameter is
- too small. (BTW, I wouldn't generally recommend polarizers with shorter
- lenses than 28mm because the effect often varies a lot over the picture
- and the sky or foliage might look weird. But it depends on various
- factors, and ymmv.)
