It is made particularly precisely so that it fits seamlessly into the camera ajonet and seals dustproof. In addition, the adapter is very stable. He can therefore also hold heavy lenses. 【Design】Connection purely mechanical, no electronic connection with the lens. Focus and aperture are performed manually on the lens. Supports manual aperture and focus (aperture has priority) and does not affect the manual exposure function of the camera. The adapter compensates for the difference between the camera's charging resolution and the contact area of the lens. Supports focus infinitely. Method of operation: The determination of the exposure time is automatically (A mode) or manually (M mode) depending on the camera model. When using custom lenses on a mount camera, you must disable the activation blocker. For this, in the menu of his camera under settings "activate without lens" you choose the option "Activate". 【Note】When disassembling, the close-up ring is removed from the camera body together with the lens and then the close-up ring is removed from the lens. For heavy medium format lenses such as telephoto lens, we recommend using a tripod clamp or a telephoto holder to compensate for the weight when recording.
