Adam Savage, one of the guys you’ll recognize from MythBusters, recently had a friend come to him in need bearing a $1,800 lens with a filter stuck tightly to the threads.
After trying, and failing, to use a device specifically designed for removing filters in such situations, Savage decides to try out some other tools in his workshop.
What’s the first thing he goes for? A bandsaw, of course.
Norm’s face looks very apprehensive as the lens inches its way towards the whirring blade. But amazingly, by cutting two holes in the lens, a wedge can then be put across the filter and used to twist it off.
It goes without saying… but you should probably never try this yourself if you value your pricey camera lens.
