Morten, I am definitely keeping it. From the perspective of a NEX user wanting more and better fast lenses, and already owning several small DSLR lenses, this is a godsend.
I will keep the really small and good CV M mount lenses like the Heliar 15 4.5 and the Nokton 40 1.4. The Ultron 28 2.0 will go, and I will stay away from large and expensive CV lenses like the 35 1.2 and the 21 1.8.
Still I haven't used it much yet, bad weather and darkness all around.
For someone wanting to step down from a FF DSLR, I am not so sure. Wide open shots for super crisp pop will suffer a bit from reduced contrast. Stopped down I am not so sure. The samples from Mike (made in a hurry) seem to indicate a bit less crispness even stopped down to f/8, something that surprises me. This may be down to camera profiles and RAW conversion, I wil try to look a bit more into it.
