Leica R on Nex
While I have no personal experience with R lenses, I recommend looking at flickriver.com, and searching for "nex leica R". You will find many good images taken with Nex cameras and Leica R lenses. Another really good source of examples is the "Nex Images Thread" at fredmiranda.com, in "Alternative Gear & Lenses".
The 60mm Macro Elmarit appears to inspire the creation of many outstanding images.
