Capture area

Sensor area indexGeometric · full frame = 100: 1.9^*
Active dimensions: 5.38^* × 3.04^* mm
Active area: 16.34^* mm²
Crop factor: 7.01^* ×
Area vs full frame: -5.72^* stops

The index is calculated from area, assuming equal scene illumination, f-number and exposure time. It is not a low-light test or an image-quality score: lens transmission, quantum efficiency, noise and processing are not included. A crop mode changes the area used, not the physical sensor.

Dynamic range ≠ EV operating range. Autofocus and metering limits describe operating conditions. Manufacturer HDR claims appear separately below; independent dynamic-range measurements require a matched test method, ISO and noise threshold.
