Just seeking clarity on this bit of info. Is it a confirmed thing or is it just a screw-up with Sony's convoluted compatibility matrix?

The LA-EA4 needs some lines of software code in the body firmware to work. The most visible piece is found in the menu system where one can do the typical for DSLR/SLT micro focus adjust, but I would guess there are also from the user hidden code that handles the communication with the adapter since it takes over the AF from the body with its own built in AF-module. And on newer bodys they don't implement this code anymore. But on those bodys the LA-EA5 works which gives a better experience.

When I put my camera in Manual mode, why don't I get any instructions?
