K&F Concept adapter rings are made of high-quality materials and to very high manufacturing standards. Made entirely of metal, they allow you to adapt optics to cameras with different mounts, so you don't have to forcibly buy a new lens for your camera.
The adapter rings are made entirely of metal (aluminum and, in some cases, also chrome-plated brass), to ensure a long product life, keeping it compact and lightweight. K&F Concept produces all its adapters using numerical control laser machines, in order to guarantee unique precision in the production of the products, to ensure full compatibility with lenses and cameras.
The adapter rings allow you to use the lenses on cameras fully manually: in fact, these adapters are without any electrical contacts. This does not affect the performance of the lens, which remains unchanged; moreover, it will still be possible to focus to infinity.
Note: using an adapter ring without electrical contacts, the camera may indicate that it is impossible to shoot as no lens is mounted; to overcome this problem, simply set the camera to Manual (M) mode or set the camera to the "Shoot without lens" function, which can be selected from the camera's menu (to find the exact location of the function, refer to the camera's instruction manual).
