Currently there are 2 native Macro Prime lenses for Nikon Z50 and all of these lenses are autofocus (AF) type.
Nikon Z50 doesn't have a sensor based image stabilization system but 1 of these Macro Prime lenses features optical image stabilization.
Since Nikon Z50 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Macro Prime lenses with Weather Sealings.
