Yes, there will be even cheaper and smaller Sony Full Frame E-mount cameras!

It took four years to get a first non Leica and affordable Full Frame camera. And now that we have the A7 and A7r Sony will not stop at all! Egami found that Sony patent describing an ultra compact Sony NEX-5 Full Frame camera! And according to one of our sources Sony will indeed launch more bodies 2014 including some that will be cheaper and smaller than the A7. It almost sounds like Full Frame and not APS-C will become the mainstream mirrorless system sensor. If Sony can keep the price down than this makes sense to create a clear advantage over the competition. The one big issue is that FF lenses will be big. On the other side you can use smaller APS-C lenses in crop mode if you care about size. Sounds intriguing!
