I have been a camera trader ever since I started with m43 in 2010. I've had a number of bodies and each of them has had great qualities and some less than great qualities as well. Prior to coming to m43 I used a Canon 10D, Olympus E500/E520 and a NIkon D40. I've had and used (in chronological order)... E-PL1 (with VF2) E-PL2 E-P1 G2 GF2 (with and without LVF1) E-P1 (a second time) E-PM1 (with VF2) When I look back at all the photos I've shot with these cameras a few things jump out at me. The IQ is so remarkably similar that I'd have a tough time telling them apart without looking at the file info in Lightroom. Next, I have found after much experimentation that I prefer having using an EVF but it can get to be very tiring on the eyes. If I could I'd rather have a nice OVF (like a Leica M or Bessa RF). To be honest my favorite camera combination was my Olympus E520 with 14-54 lens but the absolutely terrible VF on that camera was what made me sell it. I also find that I like Olympus colors but to me its not any great mystical experience. They produce nice warm pleasing colors. You can do the same in Photoshop, Lightroom, Aperture or what-have-you. I even found that you could tweak the Panasonic colors to get pretty close. I like IBIS but it wouldn't make me buy one camera over another (just like a nice stereo in a car is a cool perk but hardly the reason to buy one). I survived years without it on my film cameras so I can manage without it now. In the end I find the biggest differences are controls and how well they handle. This is the biggest differences between the cameras (to me). Of all the cameras I have had the one I regret selling is the G2. Far and away the best handling camera of the bunch and if I had it to do over again I would not have sold it. It is an outstanding body, it's IQ is similar to all the others, has a great EVF (better than the VF2 IMHO) and the articulating LCD makes for a very versatile creative tool. It also is a MUCH better body for using legacy glass with because it is stable and easy to hold. Don't care that it has no IBIS, don't care that the Panasonic color is not as pleasing as the Olympus, don't care that it's sensor is considered to be inferior. It's the best m43 camera I have had...without a doubt.
