Happening to a lesser extent bottom right too and possibly top right. I’d call it lens performance and probably a bit of decentering unfortunately. Happy to be wrong though.
Couple from the new to me S 3.5cm f/2.5. All its corners are significantly worse if it helps. And these are on a DX camera!

It's evergreens time. I have shot this view a number of times. Morning is the best time for eastern light. In the afternoon it's just long shadows from the neighbour's trees. Ever since I discovered it, I cannot unsee the mushy bottom left corner from this zoom. It is really an F8 lens as far as corner performance is concerned but there's also a chance that it's just faulty.
