Sony NEX7 with 20mm/2.8 pancake…fits all needs except macro. Same with 30/3.5 macro fits all needs except pocketability. It would even mount the FE 55/1.8 as a short tele.
From standpoint of ergonomics, Olympus Pen F would bring articulated LCD and internal stabilization, plus the ability to use my one current 4/3 lens, but it’s nearly as big as the A7R with 1/4 of the sensor size…
Looking at true subcompacts, I am unhappy both with the small sensors (1/1.7″ or even 1″) and with the slow zoom lenses. The closest I found to a usable lens seems to be the 18.5mm prime for Nikon 1…and Nikon 1 V3 seems to have all the features I like, but there’s something about that system that’s giving me pause.
One more option: dirt-cheap used Olympus EM1 (no protected viewfinder but pocketable) with Panasonic 20/1.7 pancake lens.
UPDATE: The latest contender, Panasonic GM1 with 20mm pancake lens.
