I just ordered a GX7 with the 20mm, and am struggling over which lens to complement it. I have kids so a zoom is desired. I've kind of ruled out the 14-140, because I really want the 12mm field of view for landscapes. I'm considering the 12-32mm, the 12-50mm Olympus (yes I know there will be no IS in video mode but the focal range is great), and then there is the 12-35mm f2.8. I have the 45-200mm already. The 12-32 or the Oly are lenses I could get right now, while I'd have to wait a couple months to get the 12-35mm. However, the 12-35mm used is still demanding a $900+ price tag (CDN dollars), and is getting a bit old I think. I'd really appreciate any thoughts on these. And just to throw in an alternative, what about the 14-42mm ii and the Oly 9-18??
