Mechanics

Flange back (FB, see diagram below)

-0.325mm (in glass t=0.3 IRCF)

Lens zoom structure The stepper motor is directly connected to the screw
Lens focusing structure The stepper motor is directly connected to the screw
Lens size
  • Length: 92.49mm
  • Width: 50.1mm
  • Height: 43.8mm
  • Front end diameter:  44.6mm
Weight 116g (+controller 7.8g)

In order to accommodate different image sensors, the focal distance is set back by flange back (FB) distance. The actual distance for a specific sensor has to be calculated and spacers used. If the image plane is not set correctly, focus irregularities in the projected picture are expected.fb2.png
