When i go to the camera values in the datablocks, I can change all the camera parameters:
Horizontal/Vertical FOV and the Focal Length and Sensor Size.
When I update the Horizontal or Vertical FOV, the Focal Length gets updated correctly.
When I update the sensor width or sensor height, the corresponding FOV parameter gets updated, but the Focal Length does not.
It seems to me I will make the mapping completely off and as soon as I change the sensor size, the focal length is no longer correct. Why is that? I need correct camera values including the sensor size and I am not sure right now in which combination I can achieve them.
