Notes

  1. Calculated at minimum object distance.
  2. Working distance: distance between the front end of the mechanics and the object.
  3. Percent deviation of the real image compared to an ideal, undistorted image.
  4. Typical at 30°C, 0 to ±250 mA step.
  5. Measured from the front end of the mechanics to the camera flange at infinite focusing.
