We present the Capodimonte Deep Field (OACDF), a deep field covering an area of 0.5{deg}^2^ in the B, V, R optical bands plus six medium-band filters in the wavelength range 773-913nm. The field reaches the following limiting magnitudes: B_AB_~25.3, V_AB_~24.8 and R_AB_~25.1 and contains ~50000 extended sources in the magnitude range 18<=R_AB_<=25.0. Hence, it is intermediate between deep pencil beam surveys and very wide but shallow surveys.
