I just bought a GX9 to replace my old GX7 with a broken knob. The extra mégapickles really make a difference for cropping.
At the same time, I found an almost new Panasonic Leica 12-60 mm 2.8-4.0. I used to be a prime lens guy but the quality and the versatility of this gem is really a game changer. I'm having a lot of fun with it.
