Very important for me. Alongside with volume (+ lenses volume and weight). I mountain hike over multiple days, and volume is shared with my tent, sleeping bag, food, and everything you need to that end.
I thus went with a NEX-6 back then, now replaced with an A7cII and couldn't be more pleased. Shit fattened quite a bit since the NEX-6 though.
I sometimes still use APS-C lenses for better portability, zooms especially.
