Give your Canon FD-series camera the utility it needs with the Metabones Canon FD to E-mount adapter (Black Matt). It features a true electronic integration of the aperture diaphragm, which lets the camera choose the aperture in either S or P exposure modes automatically. You can even dial it in on the camera body by yourself in either M or A modes. Both the lens and camera portion of the adapter are built from brass that is precision-machined, plated with chromium, and boasts a satin surface finish. The lens mount fits your camera with minimal effort so that there are no useless gaps or wiggling of the lens.
