Notes

  1. Calculated at minimum object distance.
  2. Working distance: distance between the front end of the mechanics and the object.
  3. Value calculated at the corner point of the sensor diagonal. For distortion graphs see datasheet
  4. Measured from the front end of the mechanics to the camera flange at infinite focusing.
