Last January the blog Photototo did a side-by-side of the A7 and the three-year old NEX7. I've always questioned the idea that full-frame should be seen as a natural upgrade from the NEX (APS-C) cameras. With the new A6000 bringing IQ equal to that of the NEX7, maybe we should be shifting our hard-earned upgrade dollars to better lenses. Sorry. Forgot to mention that Photototo is the blog of Viktor Pavlovič.
