Ha. I bought my GX8 as an experiment, mainly because of Canons refusal to produce some basic, fast EFS primes. Come on, how hard would it be to make a reasonably priced, and reasonable quality range in 15, 24, 35 and 55mm f/1.8-2 ? They've shown that they can do it with the EFM 22 pancake, but simply want to force buyers into full frame if you want fast primes. I'm not playing.
Anyway, m4/3 took on a life of its own, sold my 6D, and now I have the G9, the rest is gone It's a ripper of a camera for sure. I have the Panasonic Leica 15 mm f/1.7 20 mm f/1.7 pancake, Panasonic Leica 25 mm f/1.4, 42.5 f/1.7 and the Panasonic Leica 8-18. It's a spectacular little kit.
Fuji is about the only other maker that's seen the light, and created a proper, format specific crop system of lenses. Good on them too. I wanted the smaller size and lighter weight, so went m4/3. Very very happy I did. DFD in the G9 is spectacular I reckon. It's uncanny. As long as you give it something to work with in the viewfinder., it simply nails it. And I've only used it for a week or so
