I have to say, the Olympus 9-18mm makes an ideal backpacking lens. If it were weather-sealed, it'd be absolutely perfect. I took some 300 pictures and about half of them were with the 9-18mm. I also had the Oly 45mm f/1.8 and PL 25mm f/1.4 with me. I'm also continually impressed by how well OM-D RAW stand up to pushing and pulling. I didn't have this kind of flexibility with my G2...though I confess to, perhaps, going a bit overboard with some of the pictures here... I'm still working on processing them, but here's a handful so far from the trip.
