Important Note:
These numbers give the equivalent field angles for 35mm but should not be confused with equivalent shooting angles in the IMAX
format.  For 35mm film makers shooting in IMAX it would be best to consider using the same focal length you would normally use
and framing the 35mm image in the central thirds area to create the periferal image area for IMAX.
