Step Down Ring

If your lens has a different size filter thread to the adapter, then you can use a step-up or step-down filter ring.
This is just a metal ring with male filter threads on one side of a certain size, which screws into your lens, and a female thread on the other side of a different size, which the adapter can screw into.

The ring adapter easily screws onto the front of any lens, and converts the thread size of your lens to the thread size of any other accessory (such as filters, hoods, flashes and lens converters)
