JJC Step Up Ring 77-82mm HPRC two extra-low dispersion aspherical elementsThe Step Up Ring is a reliable and economical way to use filters. Using this ring saves you money since you won't have to buy the same filter two times for two different sized lenses. For example, a 49 52mm Step Up Ring would allow you to use 52mm filters on lenses with a 49mm front filter thread size. A series of these reasonably priced adapter rings is far less expensive than buying the same filter in two sizes.
