Two sides, two sensors, unlimited possibilities

Accurate exposure at the speed of a flash

The sensor behind the dome is a fast-response Silicon photo diode. It responds to light even in near-darkness and accurately measures exposure for the Photo ambient and Cine/video functionalities. Capture flash for those frozen-moment images even at 1/40,000s.

Two Sides, Two Sensors


Photo Ambient Exposure / Flash / Cine-Video

  • Measuring range: -4 to 20EV at ISO 100
  • Accuracy: +/- 0.1 EV
  • Light receptor: fast-response Silicon photo diode, CIE spectral luminous efficiency
  • Hemispherical Diffuser, Cardioid-type responses
  • Flash duration measurement: 1/40,000 - 1/250 s
Fast response Photo Diode


There’s more to colour than meets the eye

The sensor on the flat side is a True Color Sensor with CIE 1931 Color standard Human eye perception, one of the most accurate sensors on the market. Along with Color Temperature and Chromaticity, Illuminance is also measured with this sensor because of the cosine type response.
