K&F Concept 11in1 filter reduction ring set

The K&F Concept 11in1 set contains 11 step-up rings for attaching filters and other threaded accessories to lenses. The rings increase the accessory thread diameter, allowing larger filters, lens hoods and converters to be fitted to smaller lens threads.

Made from aircraft-grade aluminium alloy, the lightweight, durable rings have slim, polished frames for a close threaded fit. Several rings can be connected together for use or screwed into a single stack for transport. They can be used with equipment from Canon, Nikon, Sigma and Tamron, among others, where the thread sizes match.

• Included thread transitions: 26mm-30mm, 30mm-37mm, 37mm-43mm, 43mm-52mm, 52mm-55mm, 55mm-58mm, 58mm-62mm, 62mm-67mm, 67mm-72mm, 72mm-77mm and 77mm-82mm.
