Maybe, but I'd guess not.

I don't see any reason why on-sensor PDAF cannot work the older lenses, I'm just guessing it's another generation or two before they get it fully functional.

The issue won't be if focal plane AF is PDAF only and uses no CDAF. That being said, a6000 AF is good thru f/13 but after that it is CDAF.

Well, then, since the typical DSLR/DSLT always focuses with the aperture wide open then it should be an issue for pictures. Movies, on the other hand, could hit some limitations. But it would still be better than what our current SLTs allow for video autofocusing (F/3.5).

Or...are you not referring to lens aperture (F/#) but available light instead (candelas, lumens EV, etc.)?

That would actually be an A-mount advantage. E-mount uses "live" aperture but an A-mount camera will be using aperture wide open. Except when TC is in use but f/13 is pretty safe bet even with those.

Just realized there was a typo in my original message. First sentence should have been "it shouldn't be an issue", not "it should be an issue". I also expanded upon the potential video limitations.

But, yes, you are right and that was same point I was trying to make.
