Yeah, Sony need an expensive adapter to mount its own lenses ! We just been back to something that can support perfectly all the lenses that ever existed in your previous statement to something that would keep autofocus for Sony own lenses.
Look like they are exactly as the same level as any brand. They can support everything provided the registration distance of the lens you want to mount is longer the current camera registration distance and as usual the autofocus is mainl keep for the brand own lenses.
And still adapters, reduce optical quality... It has been posted before on this forum:

Not like anybody care. The guy explained, this is more than enough for a good photo. But the super extra sharpness you have with the lens... it is gone when you add the adapter.
Nobody see it because lenses are tested without adapters. So when one look at some review, he can think he still benefit of the perfect corners sharpness he dreamt about... Even through he now have very average sharpness for a good part of the image.
Does it really matter? Well it keep more sharpness than you really need for most cases... But I mean, it was already the case of the DA15 from the begining.

Originally posted by GateCityRadio IMO the A7 is a great camera and the 55 1.8 is one of the best lenses ever made, even better than the DA*55 1.4. But I'm not getting rid of my pentax stuff quite yet because of the lack of a good zeiss 85mm in the E-mount and the SR in the pentax can be a lifesaver. The A7 would be a good kit with the 35 2.8, 55 1.8, and a 85 1.8.
The reason sony is making slower lenses for the A7 is to keep the size small-ish, the same reason pentax makes all of their DA limiteds slow. The 55 1.8 really isn't that big and doesn't need the hood at all so that saves on size.
Some examples of the A7 with 55/1.8:
Thoses picture are nice... I mean 40 years olds lenses on film can achieve the same you know... And if everything is in focus, a compact could achieve the thing too if you don't need bokeh.
Not that I want to say A7 familly is unable to take great photos. Of course they can... Like all cameras.
Would the photos be that much worse with a K3 and a FA31 f/1.8 than with this A7 FF and 55 f/1.8... I'am not so sure.
Still Sony has almost no lenses nativelly available and they are all expensive. On pentax the DA35 f/2.4 achieve almostthe performance of FA31... Not in the bokeh highlight, and with some subtle rendering difference. But while not as good, it is already very good. it cost 150€ or something to buy. There nothing like that available for Sony A7 on native mount. Sony adapter is going to cost more than the lens !
It is very likely that the DA35 f/2.4 would have done just as good on 4 of the 5 photos you included ! For the first one with the OOF highlight, I would not bet on it. The FA43 would have give you likely a more 3D look, more contrast, more colors than what your actual shoots while at least on my screen on the forum size yours look quite classic and flat. But that very likely too that FA43 would have add much more disturbing out of focus bokeh too at least in 1-2 photos.
