How big the tolerance range allowed depends on the company,price of the item,etc...but there is always slight differences with anything produced in quantity.

That said,I can't recall ever returning a lens because I thought it was a bad copy.But I have seen differences in sharpness when comparing a lens I've owned with the same lens owned by a friend.

same here, robert, i own about 13-14 canon "L" lenses, 2 zeiss, and 1 sigma 150mm f2.8 macro lenses. none has been off in any way that i can put my finger on, right out of the box! so, if that is the case and this copy variation is true, at least one of my lenses should have been off in focus or something else. so far, i am not believing in this copy variation myth others' mileage may differ! happy zooming.
