It greatly simplifies the use of filters.
I've equipped all my lenses with a magnetic UV filter, or at least an adapter ring, so I can easily use and change neutral density and polarizing filters. For my rather demanding needs, the optical quality is perfectly adequate, and the filters stay securely in place. The lens cap is so tight, in fact, that I even made a small tab with tape to make it easier to remove, even with the lens hood attached.
