We analyze the bending of light by galaxies or clusters of galaxies in the
presence of the cosmological term. Going over to the Friedmann-Robertson-Walker
coordinates, used in fact for the description of actual observations, we
demonstrate that the cosmological constant does not influence practically the
lensing effect.
