Currently there are 5 native Macro Prime lenses for Sigma BF and 1 of these lenses are autofocus (AF) type.
Sigma BF doesn't have a sensor based image stabilization system and none of these lenses have optical Image Stabilization.
Since Sigma BF has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 2 Macro Prime lenses with Weather Sealings.
