The 46mm-49mm ring adapter easily screws onto the front of any 46mm lens, and converts the thread size of your lens to the thread size of any other 49mm accessory (such as filters, hoods, flashes and lens converters).
Features:
1. Use your existing 49mm filters for a wide range of 46mm lenses to avoid buying the same size filters over and over again.
2. Works with most DSLRs and SLRs, including Nikon and other brands, providing greater flexibility for photographers.
3. It is an adjustable size adapter that makes it easy for you to use the same size filter on different lenses.
