Currently there are 1 native Macro Prime lenses for Panasonic S1R and all of these lenses are autofocus (AF) type.
S1R also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on S1R.
Since Panasonic S1R has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 1 Macro Prime lenses with Weather Sealings.
