i used to work on wild/lietz,wetzlar, sokkisha, and some others- some of the japanese glass is as good or better than the german/swiss- likewise some of the stuff that used to come out of e.germany was pure crap- the best way is still to pick a quality name, but don't buy it just because it comes from europe, and pick what suits you- i've got a set of wetzlars that were only 40 bucks back in the 70's and they're absolutely perfect - no aborration, or distortion- all that said, i think that NIKON makes the best glass these days( ducks and covers)
