Finally arrived the 12mm Voigtlaender in my bag. I was very sceptical from reading about smeared edges on the a7r and very surprised HOW good this lens performs on the a7rii. even wide open the lens is tack sharp, only the extreme corners are slightly soft, which disappears completely after stopping down to f6,3 or f8. But even f5,6 is already very good over the whole frame.
Same to the voigtlaender 15/4,5 v3. Next i will buy the 21 f4, if thats similar good i will sell my trielmar wate...
