Actually, there's no such thing as "400 Speed" Kodak Infrared Film.  The
"High Speed" indicates the increase in speed from its predecessor, which
is no longer available.  You can certainly shoot the film at EI 400 (I
normally shoot 2/3 stop slower, at EI 250).

BTW, the "750" in the Konica 750 has nothing to do with film speed.  750nm
is the peak sensitivity for Konica's film.
