Removing a Broken Filter with Adam Savage

Listen in as Adam Savage  of (formerly of Mythbusters) describes removing a broken filter from a dropped Canon L lens. (Bonus points: the lens was attached to a 5D Mark IV).  In most cases where a lens has hit the ground and the filter ring becomes hard to pry off, it is better for the owner of the lens to not be present when the repair is taking place. This was pretty much the case here....

Sigma WR Ceramic Filter

This is Sigma's promo video for their line of WR glass ceramic filters.

My own test was a little less scientific. It involved repeatedly bashing on it with the butt end of a knife over lunch. Not a mark on the filter and only a few second glances from the wait staff...

Verdict: Yes it's pretty strong. Don't try the same with your fancy B+W MCR Nano filters.
