Sensor size comparison with a film slide

The sensor diagonal measures 21.6mm, which gives rise to a format factor (or crop factor) of 2.0. Hence, the Olympus E-P3 is a crop-sensor camera, as its sensor is smaller than a traditional 35mm film slide or negative.

Sensor specs and performance

The table below compares the sensor specs of the Olympus E-P3 to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
