The difference in DOF in the real world is millimeters. And really can you see that difference in a image on its own. If it was a F2 add 2k more( if were lucky) and another half a pound of weight. Sure it maybe nice to have F2 but there are penalties as well. Also the whole lens formula changes and at those wide F stops a whole barrel full of lens astigmatism will come in to play.2.8 and 2.0 is a difference in DOF and light to camera... :toocool:
Would I want one sure but this 110 2.8 is nothing to sneeze at.
