Yep, a complete departure, it would occur pre-exposure, and would
simply be positional feedback of the aperture blades (which would
relate directly to the physical size of the aperture blade opening), I
guess the lenses would have to be individually pre-calibrated and the
data stored in the on board ROM. A lot of hassle but it would be
accurate :-)
