Low-light scenes can be shot using High Base and 4000 ISO with near identical image quality to Low Base and 800 ISO. The FX9 with its secondary High Base ISO of 4000* excels in low-light conditions without adding extra gain. Its low base sensitivity of ISO 800* is similar to most other digital cinema cameras offering an excellent balance between dynamic range and sensitivity for most normal types of production. While a typical camera has a single base ISO, carefully chosen to provide the optimum settings for a wide range of shooting scenarios, the FX9’s dual ISO function offers far greater flexibility. Digital imaging sensors perform best at their base ISO as no unnecessary gain (voltage) is added to the sensor’s output.
