Hi i am shopping a new camera. I cannot decide between a7 or any price equivalent sony aps-c. what would be my advantage getting ff? is there any advance going ff ignoring the crop factor and bokeh ofcourse would be nicer cause you have you are at higher f stop. I looked up at samples but it’s very hard to come to conclusion. I care about better iso performance. And how much a7s has real life advantage over regular a7 and aps-c?
