The 4/3-inch sensor size, also known as „Four Thirds", is a standardized dimension of the image chip in the camera. This chip is responsible for converting the light passing through the lens into a digital image. The physical size of the sensor directly affects the quality of the resulting photos and videos. A larger sensor surface can capture more light, leading to better results when shooting in poorer lighting conditions, such as at dusk or under overcast skies. An image from a larger sensor contains less digital noise, which is unwanted graininess, and has a wider dynamic range. Dynamic range is the camera's ability to simultaneously capture details in both very bright and very dark parts of a scene, such as a bright sky and shadowy areas on the ground. The 4/3-inch sensor is significantly larger than the sensors commonly used in drones, such as the 1-inch or 1/2.3-inch types, and thus provides higher-quality image output suitable for more advanced creative work.
