Currently there are 6 native Macro Prime lenses for Sony A7 II and 3 of these lenses are autofocus (AF) type.
A7 II also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A7 II.
Since Sony A7 II has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 4 Macro Prime lenses with Weather Sealings.
