We present the first cosmic shear measurements obtained from the T0001 release.Similar lens signal is detected in both the r' and i' bands.Systematics are found to be statistically zero at all scales.Using multi-color information we derived photometric redshifts for each galaxy and we separate catalogues in moderate-z and high-z galaxies. We find the signal increases for the high-z sample,as expected if lensing signal is produced by cosmic shear.
