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 lenses to cameras with a different bayonet mount, so you don't have to buy a new lens for your camera.
The adapter rings are made entirely of metal (aluminum and, in some cases, chrome-plated brass), to ensure a long product life, keeping them compact and lightweight. K&F Concept produces all its adapters using laser-controlled numeric machines, to ensure unique precision in the production of the products, to guarantee full compatibility with lenses and cameras.
The adapter rings produced allow you to use the lenses on cameras completely manually: in fact, these adapters are devoid of 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: when 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 you will have to set the camera to the "Shoot without lens" function, selectable from the camera's menu (to know the exact position of the function, refer to the camera's instruction manual).
