I never actually thought I’d see a day where a protective filter for a lens could survive a very hard impact, but in a new video that Sigma released, we can see that it’s now possible using the company’s new WR Ceramic filters.
The company took their filter and many others then dropped a 1,270mm metal ball weighing 49 grams onto their filter a bunch of others. Many others shattered and broke, but Sigma’s endured. How? No idea to be honest–but if you’ve ever had your lens filter protect the front of your lens (and I surely have) then you’ll know just how great the protection is here. The video is after the jump.
