I've noticed that my 14-140 MK2 isn't is sharp as the 100-300 at 100mm. Maybe that's to be expected since the 100-300 is at its widest and the 14-140 is pushing the long end. Anyone here have both lenses and feel like comparing results? I used a tripod, IS off, E-shutter on, and 10-sec timer. Also compared it to my 14-45 at 14mm, and couldn't tell any difference in the center. The 14-140 seemed a bit sharper at the edges.
