>>4393978That lens does render flat as a board
Sony makes some good rendering zooms. The 20-70 and 16-25 are really good. But if you want RENDERING and I mean the real shit, you have to leave weather sealing behind and shoot with lenses like the 55mm f1.8 and 28mm f2, that tragically lack ass gaskets, and voigtlander stuff, which is totally non sealed. Which is a shame because the a7iv is a tank if you dont put a nonsealed lens on it.
