Gravitational redshifts and lensing by large scale structures,clusters of galaxies; (2) Redshifts and time delays of background sources; (3) Gravitational magnifications of light by very large scale structures. Observational evidence concerning some of these effects is also briefly discussed.

What the present observed lens systems tell about the lensing agent,er, the structure of an extended lens is not uniquely determined from the images. The present observed lenses are suggestive of large scale matter distribution at three scales: galaxies of core radius 1–3 kpc and mass 10. – 10..., massive dark halos of core radius 10–30 kpc and mass 10... and compac

Statistics of lensing on extended sources,nifications is two-peaked: (i)the first lies at weak amplification, while its position doesn‘t depend on the source size; (ii)the second corresponds to the largest allowed value of the amplification; this is at variance with the A. law which is found for point sources until now admitted for A ≫ 1 .T

The time delay of Q0957-+-561 A,B from 10 years of optical monitoring,est value for the time delay is now 404 days. Comparison of the brightness records shifted for the time delay shows an important discrepancy which we attribute to microlensing by a star or stars in the lens galaxy.
