But its hard to tell becuae the fat line in the middle of course is going to be easier to see than the thin lines beside it. And it says "2mm" but in the center there is little writing so there is no direct comparison. Could easily be the 2mm behind is the sharpest. I'd make a couple of different exposures too. Sometimes people breath or something. The line in the middle should not be fatter. I'd shot a ruler. Mark Rabiner New York, NY markrabiner.com
