I'm wondering if the OP understands the difference between outright lens sharpness and the lens' abilty to focus accurately.. Two entirely different thngs.. If one needs to test for outright lens sharpness one needs to focus manually, for the lens' ability to focus accurately, naturally one needs to use auto focus..

of course - there are scales for testing focusing as well.

When testing for sharpness, I always do one set manual focus, one set auto.

If for some reason the manual is sharper than the auto - then I'll do the focus testing.

I don't test lens sharpness at all! I leave testing lens sharpness to the manufacturer.

I purchase a lens and use it and have not had a problem yet, they have all met my expectations.

Funny you should say this.. In over 30 years in photography and many, many lenses later none have disappointed.. Some better than others naturally, but on the whole all have worked to their design brief..
