We present the first results of a program of observations of a sample of far galaxies ( $z_{median}=0.8$) at high spatial resolution aiming to study their morphological evolution with redshift. We observed 8 fields of $1’ \times 1’$ with the NAOS/CONICA AO system in Ks ($2.2\mu m$) band with typical $m_v=14$ guide stars. The observed fields are selected within the COSMOS-ACS and VVDS treasury survey area, in which multi-wavelength photometric and spectroscopic observations are on-going. We analyzed the morphologies by means of B/D (Bulb/Disk) decomposition using GIM2D (Simard et.al) for a number of 30 galaxies with magnitudes between $Ks=17-20$. Simulations and comparisons with CFHT and HST data have been carried out: preliminary results are shown.
