Can anyone with an OM-D plus Oly 9-18 or Pany 7-14 comment on image quality compared to the nikon setup? Since moving to m4/3, I've been committed to moving to the format completely but I'm having second thoughts. The downside to hanging onto the the nikon setup is that it would be primarily relegated to situations when I'm not trekking the camera around on my back for long distances (I'm over it), but it's very hard to justify having a dedicated wide angle for both systems (especially when I already have the 12-24 which is a great lens). On the other hand, both wide angles for m4/3's seem like compromises. Would I be happy with the quality of the 9-18 + OMD combo? The 9-14 sacrifices the ease of using filters. Decisions, decisions!
