Mechanics
| Flange back (FB, see diagram below) |
+0.93 (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 |
|
| Bare lens weight | 465g (+controller 21.4g) |
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.
