Starting a very popular but overall not very easy adaption
M/M39 lenses or Sony Bodies will be very well chosen ...
Imho my NEX-5N ist still a great performer with this kind of lenses -actual A6000 seems to be the same or better!
Voigtländer Color Skopar 2.5/75 (M39) - I like its great Bokeh (i.e. over the new 1.8/75mm Skopar with M-Mount)
