Re: RF 28-70mm soft left edge or normal performance?

Did also some close distance testing inside. Left is also here pretty bad compared to right side. Siemens stars are crops from the extreme corners. Focused camera center of the lens and took picture (ibis off) and set lens to manual focus. Moved camera on tripod head (without moving tripod) so that I could set Siemens star in the each corner and took picture and combined all in this image.

Test setup 5 images from tripod, focus center.

Some more picture can be seen on: https://mve.kuvat.fi/kuvat/Testikuvia/

Site might be slow outside Finland.

OK, maybe I'm confused but each of these clearly shows the target taken at an angle??? DOF plays a definite roll in IQ
