I try to use the cycles fisheye lens:
- with a
- camera is attached in the ceiling at
2.5min a room
- focal length is
- filed of view is
- sensor size (2/3") is
However, when I chose a large sensor, the image plane of a camera is contracted and when I chose small sensor, the image plane of a camera is extended (image2). Normally, this means that like the focal distance is changed. But, I am not sure what exactly mean because when the focal changes, the field of view changes! Any explanation will be appreciated.
