Sigma is one of the few manufacturers who produces AF lenses for Sony E-mount cameras. The 30mm F2.8 DN Art is a compact prime for Sony APS-C cameras. It has been on the market for a while, but is still one of the most popular lenses due to the combination of high image quality and reasonable price.
The Sigma MC-11 adapter allows you to use Canon EF mount lenses on a Sony E mount camera, with autofocus capabilities! Officially, only the Sigma lenses are supported, but the adapter also works with most existing Canon EF lenses. You can get it for just 150$ when it is on sale, so it is quite aggressively priced compared to similar products such as the Metabones adapter.
The 60mm F2.8 DN Art lens from Sigma is available for Micro-Four-Thirds and Sony E-Mount (APS-C only). On the latter it offers a 90mm equivalent focal length. The maximum aperture of f/2.8 makes it a suitable prime lens for e.g. portrait photography. In contrast to most other lenses in a similar price range, this lens is made in Japan.
