*Please note that your camera's lens thread size will be marked somewhere on the lens barrel. This number is always preceded by a "∅" (diameter) symbol. For example: ∅37 = 37mm lens thread size. This number can also often be found printed on lens cap's back side.

The first number is always the lens thread size, the second number is the filter size of the accessory. If the first number is bigger, it's a step-down ring. If the first number is smaller, it's a step-up.
