I have an E-P3 along with the Olympus 14-42mm kit lens and 45mm 1.8 lens. I've been thinking of adding the Lumix G X 45-175mm lens to my collection, but there seems to quite a bit of negative feedback for that lens. Is anyone using that lens with an E-P3 have any feedback? If not, what would be a good alternative? Would either the Panny 14-140 or Oly 14-150 be a better choice than the G X or the Panny 45-200 or the Oly 40-150mm lenses? Thanks in advance!
