We report the results obtained from optical and near-infrared spectroscopy and also broad-band photometry of lensed low-luminosity galaxies (1.3≤ z≤ 2.3) located in the core of lensing clusters. The amplification factor allowed us to obtain the physical properties (sfr, abundance ratios, mass, age of the burst, dust contents, etc.) of star-forming galaxies, 1 to 2 magnitudes fainter than galaxies in a blank field, using the same indicators as in studies of low-redshift galaxies. A part of this study was concentrated on the dynamics of distant lensed galaxies using integral field spectroscopy (sinfoni/VLT science verification programme).
