Sony's A-mount SLT is 'technically' a mirrorless. Demount the lens from the body and you will see the A99's full frame immediately.
I was looking at the Leica M but since getting the 40/2.8 Pancake of Canon the requirement waned.
I wish Canon's EOS M was the first sub-$3000 FF mirrorless but I guess Canon was trying to improve profit margins with their APS-C sensors.
+1. Sony has already the first full frame mirrorless Camera with AF and interchangeable lenses. The only thing missing I think is the typical mirrorless form factor. A99 even have a great AF and a very good viewfinder already. Counting the available Zeiss lenses, the realization of a full-frame with great AF, great lenses, small form factor and mirrorless isn't that far off with Sony. Sony, please make your A99 smaller...
I don't see how you can put that Sony FF mirrorless in pocket Unless, you carry a purse with you
It's not pocketable that's why I have also highlighted that fact. However, we've seen already what Sony can do with RX1. Putting the interchangeable lenses on its body will require it to bulge a little bit more. I doubt that it will be pocketable unless they create a new mount and an adapter much like what EOS-M had done.
