The black 46-52mm Step-Up Ring from Cokin 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 46mm - 52mm Step-Up Ring would allow you to use 52mm filters on lenses with a 46mm front filter thread size. A series of these reasonably-priced adapter rings is far less expensive than buying the same filter in two sizes.
- Small, efficient way to save space and money at the same time
- Allows users to buy fewer filters but continue to shoot the images they want
