Glad to hear you are really enjoying the GM5. I had a serious case of GAS on the GM5, and finally bit the bullet and bought one just a few days ago. I have been using Sony Nex for digital for many years now, while a friend had the GF1. I was always envious of him for the soft shutter feel on the Panny, and the way that 20mm pancake lens renders. The GM5 mechanical shutter feels 10 times better than the GF1 albeit 1/500 sec tops. This thing is begging for pancake lens although I have not ordered the 20mm yet, (still hoping that they will release a third version with better AF speed). I am waiting now for my Leica M adapter, so that I can slap on my MS-Optical 24mm, and really turn it into a daytime pocket street camera. Pretty impressed withe little flash as well on the manual setting, very cool!
