Panasonic Lumix DMC-GM1 review: Compact and CompetitiveBy Kevin Carter - Friday December 06 2013 Sensor Review
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.
