The step-up filter adapter ring is a versatile tool that allows you to mount larger filters on smaller camera lenses, offering several size options, including 58-82mm, 39-43mm, 49-58mm, 49-55mm, and 49-52mm. This flexibility helps save costs by eliminating the need to purchase multiple filters for different lens sizes.

Crafted from aviation-grade aluminum alloy, the adapter is corrosion-resistant and highly durable, making it suitable for various climate conditions. Its surface has been oxidized and sandblasted to minimize stray light, ensuring optimal image quality. The lightweight and compact design make it easy to carry and convenient to assemble and disassemble.

Each adapter ring comes with a vacuum-packed microfiber cleaning cloth that is specially designed to protect the coating of optical instruments like lenses and filters, ensuring a dust-free and contaminant-free cleaning process without causing any damage.
