I am also a long time duel Sony A7RX and Ricoh GRX user (X meaning I have used various iterations, not the X/40mm version of the Ricoh); and have been keeping an eye on the A7C series for when it may be worth becoming my street shooter. Would like to see it get a bit more tactile - like the Nikon ZF - and would like to see some smaller and more interesting lenses come out (like the Panasonic 18-40 and the Nikon 26 pancake or Canon 28); but nice to hear good impressions. For now it doesn't seem small enough to bring me over from true pocket point and shoots - hoping Sony comes out with something new and interesting this year from one of the RX lines.
