 From what you've quoted here, the ISO is metered without a filter (ie. no 
filter on the lens, or handheld light meter) whereas the EI given would be 
metered through the lens WITH the filter on.  Interesting that they suggest 
increasing Konica's speed in low light..  I rate mine at 12 (50 through the 
filter) and don't find any difference between 1/4 sec to 15 minutes. It'd 
be interesting to see what they consider low light to be.
