Image Size

Sensor Size (Film Gate) is the width of the medium through which an image/scene is viewed. This can range from a slide negative to a digital camera’s CCD chip. If you like you can enter the actual values from your camera to achieve a comparable focal width in Cinema 4D.

In practice however this value plays a lesser role since the part of the scene visible to the camera is generally defined by the Focal Length and the resolution’s aspect ratio values.
