Oh man, just when I thought I was done spending money on equipment for a while.
I had the same thoughts and my rationalization always was that the 14-140 is just a bit slow to justify the cost. And while I appreciate the video option in the GH1, it is only a minor criterium in my decision-making. Now, reading all this and seeing the thread with great pictures from this lens, I am wondering again... Some years ago, I really loved my little Pana FZ7 for its versatility at the time, and getting the 14-140 would bring that back, just on a higher level. I always saw myself as someone who loves tele shots, but I find myself using the 45-200 very rarely since I got it - may have to do with the fact that I am too lazy to switch lenses enough... . I do like the 14-45 very much but keeping them all AND getting the 14-140 is just not an option right now.
Sorry, just indecisive rambling. Right now, I mostly carry around the 14-45, 45-200, 20, Summicron 50 and the c-mount lens of the day. Cutting it back to 4 instead of 5 lenses for the 'small' outfit does certainly have some appeal.
