Currently there are 14 native Macro Prime lenses for Sony A7 V and 7 of these lenses are autofocus (AF) type.
A7 V also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A7 V.
Since Sony A7 V has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 6 Macro Prime lenses with Weather Sealings.
