How to solve the NEX7 lens dilemma?

A good summary Viktor

I might just add that the RJ Glassless Adapter, at least, seems to do auto focus with all Canon EF lenses.  Probably 80% accurate AF in use but also allows touch up manual focus if the shutter button if kept soft press.

It certainly has a wider range of AF options than the Metabones system.

However I would 100% endorse the Metabones Speed Booster as a very unique and effective product, a bit raw around the edges yet, but worth the money imho.
