The Ilford SFX is just an extended red sensitivity and barely
gets out into true IR wavelengths from what I have gathered. I
hear it is an off-shoot from the "traffic monitoring" films.
If you attempt using much more effective filtration than a regular
red or their filter - you won't get much onto the film.
IMO, the SFX fails to qualify as an infrared emulsion. Stick
w/ the Kodak HIE or the Konica 750nm for "real InfraRed". The
Konica "peaks" its sensitivity at ~750 nanometers whereas the
Kodak runs well out into the 900's. The SFX drops off somewhere
just past ordinary red wavelengths.
