use tripod, make sure focus is right, then shoot at f/1.4, shoot at f/2.8, shoot at f/4, shoot at f/8

post pictures of the focus area here at 100% crop, untouched.

Another way to know is that it'll write sth like Made In Chine or Made in Tihailand or Jnpan

Nikon lenses rarely have lemon copies compared to Canon. Especially the high-end ones like the 85mm f1.4. I am usually too lazy to check

When i bot my 85 1.4. The IQ of the lens is so pale. I almost given up my upgrade plan. But the salesman let me test another copy. Without changing the setting.. I saw big difference on IQ. So bot the 2nd copy. If u buy new one, best to have test at least 2 copy..

Yes, this should be the fast way, or you can shoot on a resolution chart, but difficult to interpret...

Thanks for all the replies.
I will take photo tonight and post the images here.

Any given distance from the object?
What do you mean "crop it 100%"?

Thanks,
