Ilford SFX 200 is not "true" IR film like the late,
lamented, Kodak High-Speed IR film but will give you IR
effects with a deep red filter. Check to see if your lenses
have IR markings on them. Most lenses are corrected for
visible red and typically have slightly longer focal length
for IR and deep red. If you shoot at relatively small
f/stops the depth of field will accomodate this. My main
recommendation is to test before doing any serious work. The
film should give acceptable results in any conventional
developer but I would follow Ilford recommendations.
    As I think you know exposure meters are pretty useless
for IR unless especially designed for it. Daylight exposures
are based on the average amount of IR compared to visible
light.

For development, plenty of info here:

pick the film you want, check the developers.
You will have to experiment with the exposure.
Alternatively, ask the question here:

On some Zeiss lenses for Hasselblad the infrared mark is shown
by a dotted line on the depth of field scale. Some 80mm lenses
have the mark at the f/4 line to the right. You can use this
so you focus just a little closer for infrared than for visual focus.

Thanks for the responses everybody.  The 80 mm CFi lens does have the I/R
focussing mark, and I plan on bracketing like crazy.
