Wait why doesn't it require special focusing?? I thought all IR films needed to be set to the IR mark on the lens? (The red line for the wavelength shift). I just shot my Rollie at that line, hope it comes out in focus...

The IR mark on lenses was designed with the Kodak HIE sensitivity in mind - which means longer wavelengths (900nm) and more focus shift.

The near IR sensitivity (720nm) of the Rollei film means much less focus shift.

If your shots were of landscapes, you are probably okay due to depth of field. If you were working at closer distances, you may have problems.
