B&H Photo has posted the entire line of the Sigma ceramic filters that were announced last month. The filters range from $93 for the 67mm, up to $315 for the 105mm. All of the filters are available for preorder.
Watch the video above to see what is possible with these filters. I initially thought they were a bit of a gimmick, but there may be real world uses for such protection.
