The new Sony A57 is right now in Stock at Amazon (Click here to grab it) and is the most sold Sony DSLR camera of the moment (here is the ranking). And both, the NEX-7 body only (Click here) and the NEX-7 witk kit lens (Click here) are also in Stock. And that is also the camera that makes it into the top 20 of all sold digital cameras, compact, mirrorless and DSLR.
P.S.: New Sony cameras will be announced soon. I am working to find out the right announcement date!
