The statistical gravitational lensing effects on supercluster scales are investigated. The study of Jaroszynski et al. (1990, hereafter JPPG) is followed closely, but a completely different semianalytical description of the (dark) matter distribution is introduced, and for the correlation between convergence and shear, which is neglected in their paper, is accounted for explicitly. It is found that gravitational lensing due to large-scale inhomogeneities is fairly weak and does, by itself, not affect the image properties of distant sources significantly. The present results are in remarkable agreement with those of JPPG, showing that the present model for the large-scale structure is as appropriate as their much more elaborate one for the present purposes, and that the correlation between convergence and shear has no perceptible influence.
