Last month we wrote about Sigma's announcement of their new ceramic filters which promise to add an extra level of protection for your front element over traditional glass filters, among a few other benefits. Well now there is a video to accompany those claims which goes to show just how much extra protection you can expect, and it looks very promising!
The new Sigma ceramic filters, which are now available through B&H, come with some remarkable claims that had many folks excited. They claim to be water, oil, and scratch resistant, as well as offering a 10x strength increase over traditional glass filters and a 300x strength increase over chemically treated filters.
Sigma has put together a great video to showcase that strength by dropping a 49 gram metal ball right on the filter and the results speak for themselves. As claimed by Sigma, the ceramic coated filter was the only one that survived the test.
