how is a $12-$100 adapter "considerable adaptations"? they all bolt right up to e-mount, in seconds.
i do understand the need for full compatibility, because accurate manual focusing with an ovf is nearly impossible... so dslrs need autofocus, and of course they need autoexposure, because an ovf is not wysiwg, like an evf.
b&h sells 178 slr sigma lenses, and pretty much all of 'em mount up to sony e-mount cameras... there is even a nex adapter for the sigma sa mount.

there is no shortage of lenses for e-mount.
i have also heard that canon ef-mount is slow to focus with the adapter, which is a bummer :-(
