What happens when you drop a metal ball on Sigma’s new WR Ceramic protective filter? Take a look!

In December, Sigma introduced a new line of protective filters. These filters utilize Sigma's new Clear Glass Ceramics technology and Sigma states that they are the first of their kind and the strongest in the industry.

Sigma recently shared a video on their YouTube channel that shows their new WR Ceramic Protector being subjected to a drop ball test to highlight the filter's shock resistance. Dropping a 49-gram metal ball from just over four feet (1,270 millimeters), the WR Ceramic Protector proved to be very tough.

After all, Sigma's filter is rated to be ten times stronger than a conventional protective filter and three times stronger than a chemically strengthened filter. Further, they're 50% thinner and 30% lighter than previous Sigma filters. You don't have to take their word for it though, check out the video below!

As you can see in the video, the Sigma WR Ceramic Protector handily defeated its competition. A conventional protector was shattered, a "brand 'A" chemically strengthened glass protector" was smashed, and a "brand 'B' chemically strengthened glass UV filter" was decimated by the 49g metal ball. Meanwhile, the Sigma filter looks unscathed in this impressive display.
