H&Y REVORING

REVORING from H&Y. Quite simply the world's most advanced step ring adapter ever made for a camera lens. H&Y cleverly designed and innovative variable blade technology gives any DSLR or Mirrorless camera system user the ability to use 1 single filter on multiple lenses, without the need for multiple step rings. So simple in its function, many have said: "why has this never been done before?"
