Sony has announced a couple of new cameras early this AM, including the A7 and A7R, both mirrorless interchangeable lens cameras with a twist that’s unprecedented for that type of device – a full-frame sensor is housed within each. That makes these the smallest, lightest full-frame cameras with swappable lenses to boast full-frame power, and with a 36.4 megapixel sensor on the A7R, and a 24.3 megapixel one in the A7. Of course, it’s the sheer size of those sensors that makes all the difference here.
