Are you sure you had an "infrarot" filter and not just a deep red filter? An infrared filter should be opaque to visible light, so you would not be able to see anything through the viewing lens with the IR filter attached to it . . .

The filter says "Rollei infrarot" on it. I checked focus by focusing on the element of a clear glass lightbulb. But as some have suggested, the viewing screen might not be accurate enough to show the focus shift.
