I have a saved post from long ago that suggests using a yellow filter
when using it as a convertible (assuming you're shooting B&W).  This
was to reduce the chromatic aberration that would otherwise be
corrected by the front cell.  The same poster claimed the focal length
was about 300mm for the rear cell only.

Sorry, I've never tried it myself.
