Looking for some feedback for those of you who've used the Panny 45-200 on a GF1. I'm looking for one lens beyond the 20/1.7. I don't think the 14-42 or 14-45 makes much sense, but while I like the range of the 45-200 it seems like it might just be too big for an all-purpose walk around type lens. The Oly 40-150 would be better, but I'd like stablization in this lens. What are your thoughts? Is the 45-200 just too big for the GF1? (when I say too big I suppose I mean "Should I just carry my DSLR instead?") Thanks.
