I found this lens a couple of months ago whilst doing some research on Google (I was looking for creamier bokeh LOL), a fair few reviewers (review 1, review 2) rated it over the 20mm pancake lens (which I absolutely love and is the reason why I’m into Micro Four Thirds cameras).
It’s pricey, bigger, heavier and tighter than the 20mm but I had to give it a go and I’m glad I have, it’s now my everyday set-up for the GF6 (the 20mm is back on the GF1).
PS: I’ve been geeking out about the idea of buying an even smaller camera too. My research has led me to the Panasonic Lumix DMC-LX7, which seems a lot like a GF1, but fixed lens and smaller. Then there’s the Panasonic Lumix LF1 which is truly pocketable (will easily fit in pants pocket).
