Vello has introduced a set of EXT-NZ auto focus extension rings. It is designed for Nikon Z-mount lenses. The price of the kit is $80.

Extension rings between the camera and the interchangeable lens reduce the minimum focusing distance, increasing close-ups. This is one way to organize macro photography with an existing lens without spending a lot of money on a specialized lens.

The kit includes 12 and 20 mm rings that can be used individually or together. They do not contain optical elements. The rings provide communication between the camera and the lens, so the convenience of autofocus and autoexposure functions is preserved, and if the camera or lens has an image stabilization function, it will continue to work. The advantages of rings made of metal include high strength and low weight.
