The FotodioX Contax/Yashica Pro Lens Adapter with Built-In Aperture Control for C-Mount Cameras is a high quality adapter that allows you to mount a Contax/Yashica mount lens to a C-mount camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment of the lens to the adapter. Additionally, this adapter features a built-in aperture control for determining the amount of light let into your camera.

Although the lens will fit physically, automatic lens control and functions will not operate correctly while using this adapter. You can utilize aperture priority mode in combination with stop-down metering for automatic exposure control on your camera.
