A filter adapter for camera filters is a convenient solution that attaches to your lens and works together with a filter holder. This allows you to use square filters or larger circular filters than your lens thread normally supports. Choose an adapter ring with the same thread diameter as your lens and pair it with a compatible filter holder. Do you have multiple lenses with different thread sizes? You can use an adapter ring for each thread size while sharing the same filter holder. This way, you get a flexible filter system that works with all your lenses! At Aifo, we offer a wide range of filter adapters in various sizes from renowned brands like B+W Filter and more.
