This may be the new Sony FE 20-70mm F4 G lens! According to the digicame-info, Sony will most likely announce this new lens in January/February, 2023!
Panasonic has a 20-60mm F3.5-5.6 for this kind of lens, but Sony seems to be a more versatile lens with F4 through and a longer telephoto end. However, with these specs, the size of Sony FE 20-70mm F4 G lens may be quite large.
