Just a side note, the lowest ISO isn't always the cleanest noise wise, the best is usually the base ISO, on my 5D the lowest noise is at ISO 100, ISO 50 is an expansion it's shooting at ISO 100 then dialing exposure minus one.
FWIW on my 30D I used extensively the best noise performance was at ISO 160, although it had ISO 100 and 130
