Ta for the replies, it sounds about the same as FX glass.

Often the back/front focusing won't show up or at least be obvious in real world photos. It takes a heavily cropped test image.

Because of this, some may never see it & therefore claim that all their glass was perfect out of the box, or if they did see it they may not care as it's not noticeable in a real photo.

After paying a few $k on a lens though, I'm pretty fussy & so definitely look/test for it.
