The examples shown all use an adapter without glass. It is no coincidence that the images are all at close focus. It is not possible to focus MD lenses to infinity on an alpha mount cameras without an adapter which includes an additional lens. This piece of glass will inevitably be of lower quality than any of the lens elements and will easily be the limiting factor on image quality. So MD lenses cannot be used successfully on alpha mount cameras except at short focusing distances. This phenomenon is a result ofthe differences in flange to focal plane distance of MD and Alpha mounts. The latter is greater. However, MD lenses can be used very successfully on E-mount (NEX) cameras because the flange to focal plane distance of the latter is 18mm compared with 43.5 mm on the MD mount.
Theissue is described (for Canon FD on EOS but the principle is the same) in this article.
