I continue test my lens. I've read https://www.canonrumors.com/tech-articles/how-to-test-a-lens/ article about testing. I've never tested lenses before in this way. I haven't any good printed charts for it, but i've used infinity object to test. I have attached the results. As i can see on pictures left bottom edge more softly then others.

I've create more than 20 different test: infinity object, siemens stars on the wall, led test, brick walls.
I think i have problem in left side of lens.
Other interesting thing. I test the lens on 5DM4. Also I test lens on 650D, from same distance. And on crop camera image more sharp than on full frame. Note: on full frame F4.5, on crop 2.8:

What do you think about my results?
