The first number is always the lens thread size. The second number is the filter size of the accessory. If the first number is smaller, it is step-up. Step-up ring also known as adapter ring
The LingoFoto Step-Up Filter Adapter Ring Set easily screws into the front of any lens and converts the thread size of your lens to other accessories (such as filters, hoods, flashes, lens converters, etc.)
