Test protocol FE55 , manual focus max magnification+low peaking on every f-stop (focused on tall tv/radio broadcast tower far back over horizon, focus using center of lens, but in pictures it is located on the left side of picture).

useless test because the photos are downrezzed... you don't need raw for this, ooc jpeg is generally good enough.

don't do focus/recompose for lens testing... it's probably not an issue at those distances, but it's not a good habit to be in.

you have the right idea with your setup, but you need to be up higher, with more objects to make comparisons with.

see this korean 35/1.4 junk lens test that i did, for example, at f/2, it's perfectly focused at the sign area this side of the freeway, the problem areas should be obvious:
