JJC 77mm to 82mm Step Up Ring Adapter for Camera Lens - Perfect for Macro Photography, Filter Attachment & Lens Compatibility

The 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.
