Our filter adapter rings allow you to mount filters or accessories to the front of a lens with a different thread size. In the size description the first number refers to the male thread of the adapter (which would match the thread size on the front of your lens) in millimeters of diameter, The second number is the female thread of the adapter which corresponds to the size of filter or accessory you are trying to mount to the lens. Just select the size you need from the menu above. We have hundreds of adapter rings in stock!

Important! Before you buy, make sure you have your sizes correct. Again, in the size description the first number refers to the male thread of the adapter (which would match the thread size on the front of your lens) in millimeters of diameter, The second number is the female thread of the adapter which corresponds to the size of filter or accessory you are trying to mount to the lens.
If you make a mistake and get it backwards or have otherwise ordered a size that doesn't work you can return the item, but you will be responsible for the return shipping cost and you'll get a refund for the item only (not the original shipping cost you paid). Naturally, if I mess up and send you something other than what you ordered I'll make good on it and I'll cover any shipping costs necessary even if I have to lose money to do so. Fair is fair.
