The E-mount cameras offer fast contrast-detect autofocus, while the A7RII, A7II, A6300, and A6500 also have phase-detect autofocus support. The latest Canon, Tamron, and Sigma lenses have smooth iris support, and the A7II, A7RII, and A7SII have 5-axis in-body image stabilisation. The adapter is powered by the camera body and allows for aperture control from the camera. It also has a custom function button that can be assigned to over 50 functions on select cameras. The Smart Adapter supports image stabilisation lenses and electronic manual focusing. It also has EXIF support and can display distance and zoom information on certain cameras. The adapter is compatible with both EF and EF-S lenses, but vignetting may occur with certain EF-S lenses. It has a detachable tripod foot and is equipped with a rubber gasket to protect the E-mount connection from dust and moisture. An LED indicates the adapters operation mode and communication status, and a dedicated switch controls in-body image stabilisation on Sony cameras.
