  We present deep luminosity functions derived from HST STIS data for three
rich LMC clusters (NGC 1805, NGC 1868, and NGC 2209), and for one Galactic
globular cluster (NGC 6553). All of the LMC cluster luminosity functions are
roughly consistent with a Salpeter IMF or with the solar neighbourhood IMF from
Kroupa, Tout & Gilmore (1993). They continue to rise at least to 0.7 Msun. NGC
1868 shows evidence for mass segregation which may be primordial. A comparison
of deep luminsoisty functions for seven Galactic globulars shows that the
luminosity functions are eroded at low masses by amounts that are strongly
correlated with distance from the Galactic plane.
