I used AF wit the FE28-70mm on the A6500 (full coverage with the 40-compact), it works well most of the time but not always especially at close focus and longer focal length
again that source on weibo just post rumors, yes she might work for the seminconductor industry but the most she can do is read spec sheets which has nothing to do with product planning from Sony
apparently a high end Sony APSC is coming at photokina too likely using the same sensor that allows 4k60, guess it will be priced at a higher tier than the a6500
