What is the sensor size of the Fujifilm X-A1?

The Fujifilm X-A1 is a digital camera that has an APS-C sensor at its core. This imager measures 23.5mm in width and 15.7mm in height, so that the total imaging area of the sensor amounts to 369 mm².

The X-A1 provides an image resolution of 16 megapixels, based on 4 896 horizontal pixels and 3 264 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 28.3mm, which gives rise to a format factor (or crop factor) of 1.5. Hence, the Fujifilm X-A1 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 Fujifilm X-A1 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.
