This Smart Adapter features true electronic integration of the aperture diaphragm, which lets the camera automatically choose aperture in P or S exposure modes, or dial it in yourself on the camera body in A or M modes. A wide-open button (opposite of depth-of-field preview function) makes manual focusing easy.
Powered by the camera body, it requires no external power sources, and is compatible with Arca Swiss, Markins, and Photo cam ball heads through its detachable tripod foot.
With the T version of this adapter, the inner hole is painted with flocking material coating. This can further reduce the internal reflection.
The Mark V Smart adapter are equipped with a rubber gasket to protect the E-mount connection from dust and moisture. To promote ease-of-use, an LED indicates the adapter's operation mode, optical image stabilization operation and communication status. A dedicated switch controls in-body image stabilization (IBIS) on Sony cameras equipped with SteadyShot INSIDE.
