One note about the claim of getting an EI of 1600,  that is metered through
a Wratten 87 filter. That filter passes virtually no visible light.  When
metered using an unfiltered hand held meter or when you have the filter
intalled at the film gate instead of on the lens,  the EI ranges around 10
to 25 depending upon the amount of IR in the light.  Just thought I'd clear
up that a little.
