-------------------------------------------------------
Just to emphasize, 78 degrees horizontal covers 12mm on the E-1 but is
actually midway between 24 and 28mm in 35mm film equivalent. Since the
guide number at this angle of coverage is only 28 the FL-50 is actually
a fair amount less powerful than the T-32 which claims a guide number of
32 while covering 84 degrees (24mm lens) horizontally.
