I have the LA-EA4 which allows AF with A mount lenses on full frame and APSC E mount Cameras. It works very well and does a reasonable job of extending the A mounts into the E mount systems, with a few minor downsides like no ibis, if I remember correctly. The LA-EA3 is the same but is only MF I think. The other two LA-EA1 and 2 are discontinued as they were APSC only and redundant. I would not buy a Canikon lens with adapter, too many downsides.
Sell the A6300? Why, its a good camera.
I bought the ILCE-7 (A7) together with the LA-EA4 and although I am happy with that, I must admit that a full frame E mount camera is at its best with FE mount lenses. You get in lens image stabilization and some other benefits. I am sure the same is true of the APSC E mount cameras. Unfortunately FE lenses are very expensive, that is why I only have the Sony FE 24-70mm f4 ZA OSS for the A7 (plus all my A mounts).
