NEW IN BOX - We have several copies available. Price is for 1 copy only. This Canon EOS Lens to Sony NEX Camera with Aperture makes it possible to mount a Canon EF lens to your Sony E-mount camera with a precision mechanical adapter. This adapter has an aperture, which offers manual adjustment of exposure. This adapter does not transfer functions such as auto focus from the camera to the lens, so all lens operations (focus, aperture control) are manual.
