Step Up Ring 37-49mm New but some are all blackStep up rings are used when you need to mount a filter that's larger than the diameter of your lens barrel. The first number refers to the barrel size, and the second number indicates the filter size that will fit on the ring. Step up rings are a great way to save money on filters, since instead of having to buy several different sizes of filters for your various lenses, you can buy just one large filter and several inexpensive step up rings instead.
