I'd love to know where they are going to make all these new lenses...Portugal?
Not that there is anything wrong with that. Sony has struggled with build quality of their lenses. The A7 is best in "Q" mode: put the 35/2.8 or 55/1.8 native on there and leave it. That's where the strongest results come from...well, now there is a great 90 as well. But the natives are famous for copy variation, and unlike the Q, they are no fun to MF.
Think of this: you want to make a quick landscape on a walk. With a M9, you whip out the 28 (which is a subpar FL on the Sony) high the infinity stop at F/8 and pow. With A7 and it's 35/2.8.....if you lucked out and got a good one.....you can hold it up and point it, autofocus and shoot. But where did it focus? The camera can be fickle in this situation. So, you MF, but....no infinity stop. You hit the magnifier, and.....NOISE....this is no patch LOL. You use the peaking and you frame thinking you are in a video game.
Sony's oblivious oversight in design of the focus by wire on the FE 35/2.8 defies belief. A literal headache. And for others....an opportunity.
