Does it autofocus on Sony APS-C bodies?

Yes. It is an E-mount lens with autofocus, so it works on Sony APS-C cameras such as the a6000 series and a6700.

Is it a full-frame lens?

No. It is designed for APS-C sensors and gives a 180-degree diagonal view there. On a full-frame body it will not cover the sensor.

A fisheye renders straight lines as curves and captures about 180 degrees. A rectilinear wide-angle keeps lines straight with a narrower view.

Only with care. The distortion is strong, so it suits skate, action, interiors and creative shots rather than portraits or architecture.

The lens relies on the camera body's stabilization; it has no optical stabilizer of its own.
