Well .. i tested one in a store with some outside shots against some others. Wasn't impressed but then I am a pixel peeper. I thought the Sig 17-70 might work but ended up with a Tamron 17-50 VC
KR has a review of it. http://www.kenrockwell.com/nikon/18-140mm.htm
ok ... anyone bought this lens? No reviews yet to be found. If its as sharp as the 18-135 without most of the issues then I'll be buying it.
these guys are hard to do well.
