- Andy, you need to look in the CAMERA PANEL. Lens focal length, in millimeters,
- is there, and user editable via ZOOM FACTOR. FOCAL DISTANCE is an entirely
- different setting, affecting rendered output only. Your focal length will
- determine your field of view which will alter quite noticeably how your scene
- looks within Layout. Now, I'll go so far as to say that I'd prefer to be
- able to explicitly type in the mm setting for the lens rather than fool around
- with something as arbitrary as ZOOM FACTOR for ten minutes trying to get to
- the focal length I want, but it is there.
-
- On a different note, in the current release, the FOV numbers returned look
- inaccurate. Comparing the numbers in lightwave with corresponding values
- in the lens tables found in the Cinematographers handbook show that the
- aspect ratio of your FOV should match the aspect ratio of your aperture and
- your image, and they don't.
