Sony has officially announced the 66.8MP back-illuminated stacked sensor A7R and their new telephoto lens 100-400mm f/4.5 lens. The lens weighs in at 1.84 kg, which will be about 2 kg with hood. I would be using such a lens most of the time with a 2xTC on it to give a 200-800mm f/9, which would be heavier than the RF 200-800mm f/6.3-f/9, and narrower through the shorter focal lengths.
