We just upgraded our Technical Photography equipment with Xume Magnetic Filter Adapters.  They allow to quickly snap-on filters without any need to screw them. This saves threads on lenses and filters.  Xume adapters make Technical Photography workflow much faster.

XUME Adapters utilize NdFeB rare earth magnets. I didn’t see any risk of harm to my camera, other electronics or storage media with the use of this product.
