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. For RT-V0828-MPY2, with a 1.1 sensor it must be used an RT-VM0811 mount adapter for M72 x 0.75 filter mount. With a 1" sensor, it could be used an RT-VM0810 mount adapter for M67 x 0.75 filter mount.
  5. Measured from the front end of the mechanics to the camera flange at infinite focusing.
