My response to "Why do Nikons use H 0.3, 0.7, 1.0 and 2.0 instead of ISO 12,500, 16,000 etc." were always answered with, "Because the ISO (International Standards Organization) does not recognize any film or digital speed higher that 10,000. So to avoid getting into trouble, Nikon uses the H designations."
Well, my theory worked until I got my D600. And instead of finding ISOs of 80, 64 and 50 (familiar ASA numbers from my film days), I find L 0.3, 0.6 and 1.0.
Obviously, ISO speeds of 50, 64 and 80 exist and are perfectly acceptable by the ISO. So why use the L system instead of actual ISO ratings that have existed for years?
FWIW, if given my druthers, I'd like to see a DSLR with a range of ISOs from 10 up to 1600 max.
