What is the sensor size of the Olympus E-P7?

The Olympus PEN E-P7 is a digital camera that has a Four Thirds sensor at its core. This imager measures 17.4mm in width and 13.0mm in height, so that the total imaging area of the sensor amounts to 226 mm².

The E-P7 provides an image resolution of 20.2 megapixels, based on 5 184 horizontal pixels and 3 888 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 21.7mm, which gives rise to a format factor (or crop factor) of 2.0. Hence, the Olympus E-P7 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-P7 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.
