Currently there are 12 native Macro Prime lenses for Sony A99 II and all of these lenses are autofocus (AF) type.
A99 II also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A99 II.
Since Sony A99 II has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Macro Prime lenses with Weather Sealings.
