Courtesy of SonyAlphaRumors, here is a verified sketch of the upcoming A7 & A7r cameras. These will feature full-frame sensors, weather sealing, and Sony’s E-mount. They will not have in-body image stabilization (like Olympus does) or the NEX-7 tri-navi control system. The A7 is rumored to have phase-detection sensors on the image sensor (like the NEX-6 and OMD-M1) whereas the 36MP A7r does not. However, the autofocus of the A7r is said to be “different” so perhaps we’ll see the return of Sony’s funky holographic-laser AF.
The official announcement is October 16, 2013.
