For this Rokinon, no adapter will add autofocus or camera-controlled aperture. It’s a fully manual lens, so it has no focus motor and no electronic interface for the camera to drive.

Some specialty lens modifications exist for certain older lenses, mainly to add limited electronic communication such as aperture reporting, focal length data, or camera integration features. But that depends on the specific lens design and is not a general adapter solution. It also does not mean autofocus can be added to a purely mechanical manual-focus lens.

In practice, with a manual lens on the Sony A7, you’ll use the aperture ring on the lens and focus manually. The A7’s manual-focus aids, such as focus magnification, are the main workaround and are often the best way to use lenses like this.
