The Pro Lens Mount Adapter for Contax 645-Mount Lens to Sony E-Mount Camera from FotodioX allows a Contax 645-mount lens to be used with a Sony E-mount camera. The adapter is designed to support focusing to infinity, is constructed from brass and aluminum alloy, and features stainless steel lens mounting rings to provide a durable yet lightweight camera-to-lens or camera-to-adapter connection.
This lens adapter does not support electronic communication between an attached camera and lens, so lens functions that rely on electronic communication with the camera body, like autofocus, AE metering, and image stabilization, will not function. To manually control the amount of light that enters a Sony E-mount camera when using this adapter kit, an integrated iris mechanism allows for approximate adjustments of brightness as well as depth-of-field.
