Made from highly refined bronze and chrome plated with a fine finish. This adapter allows to use T Mount lens on a Canon EOS camera body. Since the adapter does not provide electrical contact translation, automatic diaphragm, auto-focusing, or any other functions will not operate correctly. In this case "stop-down mode" will need to be used when metering.
The through-the-lens exposure metering function is supported. The T Mount lens has to be set to manual mode or aperture priority. Focusing can be infinity.
