Trailing main rivals by 18-20 points on our DxOMark Sensor score, the older sensor of the GF6 is looking quite dated, and, as a result, the sensor metric scores make somber reading. Color depth is -1.33 stops under both cameras, while DR is close to -2 stops on average. While the camera’s feature set is similar this is a subpar result overall, especially against the similarly priced E-PL5 (given the same pixel count and equal size sensor). Indeed if price is a concern, at $499 including the 16-50mm kit zoom, the Sony is the ‘winner’ here.
With just one point difference between the Lumix DMC GF6 and the much earlier (2011) enthusiast-oriented GX1 (and with it, correspondingly similar sensor metric scores), it’s safe to assume the two adopt the same sensor.
Compared to the Nikon 1 S1 the GF6 doesn’t fare that well either, given the smaller (CX) sensor of the former. In fact, the two are surprisingly similar in performance terms though the +0.66 stop advantage of the GF6 in low light is not a surprise and genuinely useful. While the $499 Nikon (c/w 11-27.5mm kit lens) is the value choice between them, the sensor is a now somewhat lowly 10.1 MPix unit.
