If my quick calculations are correct, the use of either a 50mm or 100mm lens would give the following FOV (degrees) using popular KAF CCD sensors: Lens FL KAF-400 KAF-1600 KAF-3200 50mm 5.3 x 7.6 10.5 x 15.7 11.5 x 17.0 100mm 2.6 x 3.8 5.3 x 7.9 5.7 x 8.5 >From the above it is evident that those of us with the most common KAF400 won't be able to meet the 10 deg criteria, unless we use a 'fish-eye' :-) Larger chips won't have a problem.
