The comment about the 21mm and color shifts has nothing to do with adapters though and everything to do with how RF lenses are designed and their inherent incompatibility with digital sensors. Leica had to pull off some serious engineering to get a full frame to mostly work with RF glass. The Nex6 seems to correct for RF lenses, so maybe sony spent some development on this, but the comment about the 21mm is very telling that some people expecting a cheap Leica are in for some real disappointment.
