To everyone:
I had Sony SEL50 sample which passed this test perfectly but one corner was rather bad.
Be sure to check if all corners have same quality/resolution even if this test shows no issues.
Frank:
If you can exchange this lens with no question asked - just do it.
Getting some pictures that clearly show sharpness issues (like weak side/corner) should be helpful in most other cases.
