"What does your product do ?
Our product is a set of replacement parts for converting a Contax N-mount lens to Canon EF-mount. After the conversion the lens will stop down the aperture and autofocus as commanded by the camera body.
How does your product work ?
A microcomputer emulates a N-mount camera while talking to the lens, and emulates an EF-mount lens while talking to the camera body."
