Sure, but the Voigtlanders come with a CPU for proper EXIF, aperture, focus distance communication and can trigger the focus assist automatically when desired.
The 40/1.2 full frame lens has a decent following in the Sony camp as it combines the perfect balans of the fast aperture, fantastic boke, sharpness, small size and smooth controls of an old skool lens combined with all the mentioned benefits of a modern lens.
There are plenty manual focus lenses out there like Laowa 35mm 0.95 but I am kind of done with lenses without a CPU.
