This Stepping Ring enables a filter with an attachment (62mm Filter / Tube Adapter / Lens Hood / Lens Cap) size of 62mm to be used with a lens of 49mm.
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.
Still confused email us to clear it up further and also look at second picture that will help you understand.
