Step-Up Ring: 72mm Threaded to 80mm Outer Rental

A step-up ring refers to a photographic accessory that allows the attachment of a filter or lens with a larger diameter to a camera or lens with a smaller thread size. In this specific case, the step-up ring has a 72mm threaded inner side and an 80mm outer diameter. This means that it can be used to connect a lens or filter with an 80mm thread to a camera or lens with a 72mm thread. The step-up ring acts as an adapter, ensuring a secure and precise fit between the two components, allowing photographers to expand their equipment compatibility and maximize the creative possibilities of their gear.
