According to latest rumors, Sigma will soon announce the development of Sigma 24-70mm f/2.8 DG DN Art Lens for L-mount. This will be the fourth Sigma L-mount native lens. The official announcement will be on November 6th, 2019.
Here is a video comparison of new released Sigma fp compared to Panasonic Lumix S1 full frame mirrorless cameras. Both cameras used the Sigma 45mm f/2.8 DG DN Contemporary lens. From the video, we can see that Eye-AF of Panasonic Lumix S1 is much better than Sigma fp.
