I'm pretty new to MFT still. Shooting an Olympus E-P3. What I'm looking for is a 2-lens vacation kit. With my 5DM3 I carry these: 70-200 f/2.8 IS 17-40 f/4 In terms of focal range and speed I absolutely couldn't ask for anything more. I spent two weeks traveling through Greece and Turkey and these lenses literally covered everything I wanted to shoot. I wanted for nothing, other than a lighter setup! The replacements I'm considering in the MFT world are: Panasonic 35-100 f/2.8 Olympus M ED 9-18mm f/4.0-5.6 I'm guessing the 35-100 is a no-brainer, as the specs match and the user reviews seem to be good. Though I suspect I may be over-paying a bit for the O.I.S. since Olympus does it in-camera (rendering lens-based IS useless, I'm guessing). The Oly 9-18 is close enough in focal length, though I'd sure like the f/4 speed when zoomed in. Does this sound like a good match? Are there better matches out there? Are there 3rd party lenses (not Oly or Pano) I should be considering? Thanks.
