  I show that the lensing masses of the SLACS sample of strong gravitational
lenses are consistent with the stellar masses determined from population
synthesis models using the Salpeter IMF. This is true in the context of both
General Relativity and modified Newtonian dynamics, and is in agreement with
the expectation of MOND that there should be little classical discrepancy
within the high surface brightness regions probed by strong gravitational
lensing. There is also dynamical evidence from this sample supporting the claim
that the mass-to-light ratio of the stellar component increases with the
velocity dispersion.
