Where is the Iris on video camera?

Is the iris in the lens, part/attached to the CCD, or after the CCD? A diagram would be useful.

Where is the Iris on video camera?
If you start from the glass end of the lens the front part is the focus, then behind that is the zoom, then comes the iris, then comes the back focus/macro then comes the CCD. Its definatelty part of the lens. Its not usually accessible on a lot of domestic video cameras, although some give you some kind of electronic control over it. Its quite easy to see on any kind of serious lens such as that on a broadcast camera.
Reply:Usually between elements in the lens. Near the rear.





Althought in home camcorders it could be behind the lens.
