<div class="helpdiv"> The value depends on the size of the optical sensor chip of the camera.<br/> For full frame cameras the value is "1.0". For cameras with smaller chips, please refer to the cameras technical specifications. <br/><br/> Common values are between 1.5 to 1.6. The crop factor is the same factor that affects the focal length of your camera's objective. <br/>E.g. the focal length of an objective with a full frame camera is 50mm. With a camera that has a crop factor of 1.5 the effective focal length would be 1.5 x 50mm = 75mm. <br/><br/> <strong>Default Value:</strong> 1.0 </div>
