What is the crop factor of the Leica S1?
The Leica S1 Pro is equipped with a medium format sensor, whose diagonal measures 50.9mm. The sensor has a crop factor (or format factor, or focal length multiplier) of 0.85.
The crop factor is defined as the ratio of the 35mm full-frame film diagonal to the diagonal of a digital sensor. This number indicates how a lens behaves in relation to the size of the image sensor.
Sensor size comparison with a film slide
With a crop factor of 0.85, the sensor in the Leica S1 is larger than the receptor area of a 35mm film slide or negative. As a result, a lens that is attached to the Leica S1 will offer a wider angle of view and provide shallower depth of field than a lens of similar focal length and aperture on a film camera. The equivalent focal length is obtained by multiplying the actual focal length of the lens with the crop factor. For example, a 59mm lens on the Leica S1 will provide the same angle of view and depth of field as a 50mm normal lens on a film camera (59mm * 0.85 = 50mm).
Sensor specs and performance
The table below compares the sensor specs of the Leica S1 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.
