Cautious flexibility
Step-down filter adapter rings add flexibility to your filter adapter options, but a little common sense is required regarding their application. In this particular case, I wanted to use 46mm filters in a 49mm front-and-rear-threaded lens shade, which I've adapted to a 37mm threaded lens via a 37-49mm step-up ring (49mm was the smallest thread size this shade was available in, and I also needed the larger shade for unobstructed use on a wide angle lens). This works solely because the 46mm filters (I wanted to maintain this common filter size for all the lenses I have for my Lumix GX7) are sufficiently larger that the lens' 37mm thread to avoid vignetting. Trying to use 46mm filters on a 49mm threaded lens, for instance, will almost always result in vignetting (especially with wide-angles), although you might get away with it for macro applications, since optical parameters are somewhat narrower at very close focusing distances. You can buy cheaper adapter rings than Tiffen, but Made in U.S.A is worth the difference to me.
