A new photometric system suitable for deep, precise and quick metallicity
mapping in galaxies is proposed. We find a linear correlation between our
metallicity index and the Mg2 index for stellar, globular cluster, and
early-type galaxy spectra, and model spectral energy distributions of the
simple stellar populations.
