Sensor Review
Introduction | Panasonic Lumix DMC-GM1 sensor performance: Good but not great | Panasonic Lumix DMC-GM1 vs Nikon 1 J3 vs Olympus PEN E-PM2: Competitive Performance? | Conclusion

Against similar rivals in the marketplace the GM1 outperforms the Nikon 1 J3 with its smaller 1-inch type sensor by 14 points, or the equivalent of  around +1 stop in image quality.

The Panasonic has more than 1 stop better color discrimination compared to the Nikon at base sensitivity, and just over +2/3 stop more dynamic range. And it’s no surprise to see the Lumix better the smaller chip by around +1/2 stop in low light performance.

Side-by-side with the 16-Mpix Olympus PEN E-PM2, which was launched alongside the E-PL5 at Photokina last year, the Lumix is around -1/3 stop behind in IQ overall. This can be broken down individually as having a -1/3 stop less color depth, -1/2 stop less exposure range (DR), and quite a noticeable -2/3-stop disadvantage in low light capability.

That’s not quite as discouraging as it sounds, as in low light the E-PM2 is sport the best performing MFT sensor model in our database.
