Comments.Text: I don't know anything about the camera you mentioned, but certainly higher end cameras shoot different resolutions. They often do this by cropping the sensor, but also by "pixel-binning", where adjacent pixels are averaged

  No, there is physically only one 'native resolution' for any hardware sensor. It is the number of physically distinct light sensitive areas on the sensor chip and is set in silicone at the time of manufacture.
  
  When OBS or any other software gives you a different sized image it is either re-sampling using the values available from the native resolution or alternatively changing the camera resolution which then puts the burden of re-sampling on the cameras internal processing chips.
