I have a GF1 which I use as a second camera. Main rig is D90 with several lenses. Am intrigued with 4/3 system and thinking about getting the 14-140 lens, but not to use on the GF1. Thought that lens with a G2 or GH1 body would be the ideal travel camera rig. Really want a viewfinder for using a long lens like that and the clip-on for the GF1 is not that great from what I hear. Any thoughts?
