Reply to Vignetting effect

Thanks for the advice, I tried it with High settings, same result.
I also tested it with another lens 50mm 1.8G, no vignette effect appears.
If I can’t make any solution for this problem, which lens you had proposed to me to get for the weddings, which has a similar price as 24-120mm f/4
because for 24-70 f/2.8 I have no budget.
