Hama Step-up adapter ring

Hama Step-up adapter ring

The Hama Step-Up thread conversion ring (stepping ring, adapter ring, thread adapter, thread adapter) allows you to change the filter thread of your lens to a larger size. This is especially necessary when you want to attach a filter or teleconverter to threads with a smaller diameter.

The first number in the product name is the male thread, i.e. the size of the lens thread, and the second number is the larger female thread, i.e. the size of the filter to be used. In other words, if, for example, the camera lens has 72mm threads and you want to attach a 77mm filter to it, you will need a 72-77 Step Up adapter. The parts will not be attached with a 77-72 Step Down adapter.
