Approximate area only. Width and height are unknown, so no sensor outline or crop factor is inferred.

Sensor area indexEstimated · full frame = 100From native pixel pitch and sensor resolution.: ≈ 14.8^*
Active dimensions: —
Estimated area: ≈ 128^* mm²
Crop factor: —
Area vs full frame: —

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.
